GENERAL DESCRIPTION
The ADuC7023 is a fully integrated, 1 MSPS, 12-bit data acquisition
system, incorporating high performance multichannel ADCs,
16-bit/32-bit MCUs, and Flash/EE memory on a single chip.
The ADC consists of up to 12 single-ended inputs. An additional four
inputs are available but are multiplexed with the four DAC output
pins. The ADC can operate in single-ended or differential input modes.
The ADC input voltage is 0 V to VREF. A low drift band gap reference,
temperature sensor, and voltage comparator complete the ADC
peripheral set.
The DAC output range is programmable to one of two voltage ranges.
The DAC outputs have an enhanced feature of being able to retain
their output voltage during a watchdog or software reset sequence.
The devices operate from an on-chip oscillator and a PLL, generating
an internal high frequency clock of 41.78 MHz. This clock is routed
through a programmable clock divider from which the MCU core
clock operating frequency is generated. The microcontroller core is an
ARM7TDMI®, 16-bit/32-bit RISC machine that offers up to 41 MIPS
peak performance. Eight kilobytes of SRAM and 62 kilobytes of
nonvolatile Flash/EE memory are provided on chip. The ARM7TDMI
core views all memory and registers as a single linear array.
The ADuC7023 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 are supported.
On-chip factory firmware supports in-circuit download via the I2C
serial interface port, and nonintrusive emulation is supported via
the JTAG interface. These features are incorporated into a low cost
QuickStart™ development system supporting this MicroConverter®
family. The part contains a 16-bit PWM with five output signals.
For communication purposes, the part contains 2 × I2C channels that
can be individually configured for master or slave mode. An SPI
interface supporting both master and slave modes is also provided.
The parts operate from 2.7 V to 3.6 V and are specified over an
industrial temperature range of −40°C to +125°C. The ADuC7023 is
available in either a 32-lead or 40-lead LFCSP package. A 36-ball
wafer level CSP package (WLCSP) is also available.
