The ADuC7124 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 two inputs are available but are multiplexed with the two DAC output pins. The ADC can operate in single-ended or differential input mode. The ADC input voltage range 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 three 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 device operates 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, which offers up to 41 MIPS of peak performance. Thirty-two kilobytes of SRAM and 126 kB of nonvolatile Flash/EE memory are provided on-chip. The ARM7TDMI core views all memory and registers as a single linear array.
The ADuC7124 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 UART serial interface port or the I2C port, while nonintrusive emulation is also 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 six 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. Thirdly, 2× UART channels are provided. Each UART contains a configurable 16-bit FIFO with receive and transmit buffers.
The part operates from 2.7 V to 3.6 V and is specified over an industrial temperature range of −40°C to +125°C. When operating at 41.78 MHz, the power dissipation is typically 120 mW. The ADuC7124 is available in a 64-lead LFCSP package.
