Preliminary Technical Data ADuCRF101

GENERAL DESCRIPTION

The ADuCRF101 is a fully integrated data acquisition solution
designed for low power wireless applications. It features an 14­bit ADC, a low power Cortex™-M3 core from ARM®, a
431 MHz to 464 MHz and 862 MHz to 928 MHz RF transceiver,
and Flash/EE memory packaged in a 9 mm × 9 mm LFCSP.

The acquisition section consists of a 14 bit SAR ADC. The six
inputs can be configured as single ended or differential modes.
When configured in single ended mode, they can be used for
ratiometric measurements on sensors, powered when required
from the internal LDO. An internal battery monitor channel
and an on-chip temperature sensor are also available.

This wireless data acquisition system is designed to operate in
battery-powered applications where low power is critical. The
device can be configured in normal operating mode or different
low power modes under direct program control. In flexi mode
any peripheral can operate and wake-up the device. In
hibernate mode the internal wake-up timer remains active. In
shutdown mode only an external interrupt can wake-up the
device.

The ADuCRF101 integrates a low power Cortex-M3 core from
ARM. It is a 32-bit RISC machine, offering up to 1.25 DMIPS
peak performance. The Cortex-M3 MCU also has a flexible 14­channel DMA controller supporting communication
peripherals SPI, UART and I
Flash/EE memory and 8 kB /16 kB of SRAM are also provided
on-chip.

2

C. 64 kB / 128 kB of nonvolatile

A 16 MHz on-chip oscillator generates the system clock. This
clock can be internally divided for the CPU to operate at lower
frequency for power saving reasons. A low power internal 32
kHz oscillator is available and can used to clock the timers.
There are two general-purpose timers, a wake-up timer and a
system watchdog timer.

A range of communication peripherals can be configured as
required in a specific application. These peripherals include
UA RT, I

The RF transceiver communicates in the 431 MHz to 464 MHz
and 862 MHz to 928 MHz frequency bands using multiple
configurations.

On-chip factory firmware supports in-circuit serial download
via the UART while nonintrusive emulation and program
download is also supported via the serial wire interface. These
features are incorporated into a low cost development system
supporting this precision analog microcontroller family.

The parts operate from 2.2 V to 3.6 V and are specified over an
industrial temperature range of −40°C to +85°C.

Three versions of the ADuCRF101 are available:

14-bit ADC, 128k Byte Flash and 16k Byte SRAM,

12-bit ADC, 128k Byte Flash and 16k Byte SRAM,

12-bit ADC, 64k Byte Flash and 8k Byte SRAM,
