GENERAL DESCRIPTION
Auxiliary (24-bit) ADC: 4 differential pairs or 7 single-
ended channels
The ADuC706x series are fully integrated, 8 kSPS, 24-bit data acqui-
sition systems incorporating high performance multichannel
sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), 16-bit/
32-bit ARM7TDMI® MCU, and Flash/EE memory on a single chip.
On-chip precision reference ( 10 ppm/°C)
Programmable sensor excitation current sources
200 μA to 2 mA current source range
Single 14-bit voltage output DAC
Microcontroller
ARM7TDMI core, 16-/32-bit RISC architecture
JTAG port supports code download and debug
Multiple clocking options
The ADCs consist of a primary ADC with two differential pairs or
four single-ended channels and an auxiliary ADC with up to seven
channels. The ADCs operate in single-ended or differential input
mode. A single-channel buffered voltage output DAC is available
on chip. The DAC output range is programmable to one of four
voltage ranges.
Memory
32 kB (16 kB × 16) Flash/EE memory, including 2 kB kernel
4 kB (1 kB × 32) SRAM
Tools
In-circuit download, JTAG based debug
Low cost, QuickStart™ development system
Communications interfaces
The devices operate from an on-chip oscillator and a PLL gene-
rating an internal high frequency clock up to 10.24 MHz. The
microcontroller core is an ARM7TDMI, 16-bit/32-bit RISC
machine offering up to 10 MIPS peak performance; 4 kB of SRAM
and 32 kB of nonvolatile Flash/EE memory are provided on chip.
The ARM7TDMI core views all memory and registers as a single
linear array.
SPI interface (5 Mbps)
4-byte receive and transmit FIFOs
UART serial I/O and I2C (master/slave)
On-chip peripherals
4× general-purpose (capture) timers including
Wake-up timer
The ADuC706x contains four timers. Timer1 is a wake-up timer
with the ability to bring the part out of power saving mode. Timer2
is configurable as a watchdog timer. A 16-bit PWM with six output
channels is also provided. The ADuC706x contains an advanced
interrupt controller. The vectored interrupt controller (VIC) allows
every interrupt to be assigned a priority level. It also supports
nested interrupts to a maximum level of eight per IRQ and FIQ.
When IRQ and FIQ interrupt sources are combined, a total of 16
nested interrupt levels is supported. On-chip factory firmware
supports in-circuit serial download via the UART serial interface
ports and nonintrusive emulation via the JTAG interface. The parts
operate from 2.375 V to 2.625 V over an industrial temperature
range of −40°C to +125°C.
Watchdog timer
ꢀectored interrupt controller for FIQ and IRQ
8 priority levels for each interrupt type
