 ARM7 Core Products with Precision 12-Bit Analog I/O (ADuC7019 to ADuC7028, ADuC7128, and ADuC7129)
Architectural Overview
The ARM7TDMI core is a 32-bit RISC machine. It uses a single 32-bit bus for instructions and data. The TDMI option provides four additional features:
a secondary 16-bit Thumb (T) instruction set, debug (D) support, support for long multiples (M), and includes the embedded ICE (I) module containing
the breakpoint and watchpoint registers, which allow code to be halted for debugging purposes.
Each ADuC7xxx device operates from an accurate (±3%) on-chip oscillator and PLL generating an internal 41.7 MHz clock that is routed through a
programmable clock divider from which the MCU operating frequency is generated. Alternatively, the parts can run from a master clock up to 44 MHz.
2
Power consumption is 1 mA/MHz.
Either 126 kB, 62 kB, or 32 kB of nonvolatile Flash/EE and 8 kB of SRAM are provided on chip with both blocks mapped into a single linear array.
ARM code can run directly from SRAM at 41.7 MHz/44 MHz (internal/external clock), given that the SRAM is configured as a 32-bit wide memory
array. The 80-lead devices support external memory.
On-chip firmware supports in-circuit serial download via the UART or I2C® and JTAG serial interface ports while nonintrusive emulation is also
supported via the JTAG interface.

Integrated Battery Sensor for Automotive Battery Monitoring Includes High Voltage Physical Interface for LIN
ADuC703x Family
The ADuC703x family of automotive battery monitor solutions addresses a growing need to monitor and distribute power, and provide priority
to critical functions such as engine startup. The ADuC703x family measures elementary physical variables such as battery voltage, current, and
temperature to determine the battery’s state-of-charge (SOC) and state-of-health (SOH). The vehicle’s energy management system then uses this
data to reserve sufficient battery energy for a guaranteed engine start and to tailor the charging cycles resulting in reduced fuel consumption.
The ADuC703x family integrates an on-chip PGA (programmable gain amplifier) for a wide range of battery current measurements and, similarly,
attenuation for battery voltage measurement. Also on board are up to three 16-bit analog-to-digital converters (ADCs), an ARM7 microcontroller, 5
a local interconnect network (LIN) transceiver, and embedded memory in a single package. The devices offer a cost-efficient and space-saving
alternative to discrete solutions, which consists of a standalone processor, LIN transceiver, low dropout regulator (LDO), and analog front end (AFE).
As a result, the component can be located between the battery terminal and the connector on the main power cable, giving a great saving in space
and cost, while simplifying overall battery monitoring system design.

 Application Focus: Electrocardiogram Using ADuC7021
An electrocardiogram (ECG) is the recording of the electrical activity on the body surface generated by the heart. This electrical activity is collected by
skin electrodes placed on predetermined parts of the body. A low cost implementation of an ECG monitor is shown in the schematic here, and for the
main signal processing, the ADuC7021 MicroConverter device is chosen. This part features the necessary high performance analog peripherals, a fast
ARM7 core, integrated 62 kB flash for code, and several other useful peripherals. The ADC converts the analog signal from the differential amplifier to
a digital signal. The software, resident in the ADuC7021 flash, then processes the digitized signal to produce the final ECG trace. Because of the flash-
based code memory on the ADuC7021, this customization can be done after manufacture or even as the individual patient’s needs change.

Application Focus: Pulse Oximeter Uses ADuC7024

Beyond heart rate, blood pressure, respiratory rate, and temperature—pulse oximetry is considered to be the “fifth vital sign” of health status.
A pulse oximeter is a medical device that provides a noninvasive measure of the amount of oxygen in a patient’s arterial blood.
A typical oximetry sensor has a pair of light-emitting diodes (one red with 660 nm wavelength, one infrared with 940 nm wavelength) facing a
photodiode through a translucent part of the patient’s body, usually a fingertip or an earlobe. The percentage of blood oxygen is calculated based on
the absorption rate from each wavelength of light after it passes through the patient’s body.
The precision analog microcontroller family of products from Analog Devices includes the key analog building blocks required for high end oximetry
designs. The ADuC7024, used here, includes a high performance, high speed, multichannel, 12-bit, 1 MSPS ADC and two DACs. The MicroConverter
device also includes a 32-bit ARM7TDMI core. Running at 41.8 MHz, it provides a very powerful computational platform for digital signal processing
algorithms to detect arterial blood pulsations, while allowing plenty of CPU performance for additional functions, such as control of the graphics LCD
display. The ADuC7024 MicroConverter device features 30 general-purpose I/Os (GPIOs), required for interfacing with the LCD. With fewer I/Os, the
same level of performance can be achieved by using the ADuC7021, available in a space-saving 6 mm × 6 mm LFCSP package.

Precision Analog Microcontroller with Unequalled Data Acquisition and Processing
Performance for Industrial and Instrumentation Applications
ADuC706x Family
The ADuC706x family of ARM7 microcontrollers with best-in-class data conversion performance is ideal for industrial systems
engineers designing smart sensing, factory automation, and instrumentation equipment.

ADuC7060 incorporates two 24-bit Σ-∆ ADCs and a host of analog peripherals with ARM7 core to create a solution for precision
sensing applications. The integration of a 32-bit RISC MCU, flash memory, and high resolution data converters in a small footprint,
combined with low power operation eliminates the complexity, cost, and performance degradation issues associated with discrete
mixed-signal solutions.
Designed to support 4 mA to 20 mA loop-powered applications and precision instrumentation, the 24-bit Σ-∆ ADC provides the
resolution required by high performance industrial and instrumentation equipment, while keeping the noise low at just 60 nV.
This performance combined with an ARM7 provides a single chip solution that can handle all data acquisition, processing, and
communications functions at the sensor node.
In addition to the 5-channel, 24-bit Σ-∆ ADC with PGA and the ARM7 core with eight interrupt priority levels, the ADuC706x
products integrate 32 kB flash memory and 4 kB SRAM, a 14-bit DAC, multiplexers, buffers, an auxiliary 8-channel, 24-bit ADC for
cold junction compensation in thermocouple applications, and SPI, UART, and I2C ports. Operating current is just 2.6 mA with all
peripherals activated.
