Mixed-signal ARM7 MCU in a 5x5 LFCSP
The ADUC7023BCPZ62I-R7 carries eight 12-bit ADC channels and four 12-bit DAC outputs.
What the 44 MHz core and 62 KB Flash mean for the BOM
The 44 MHz ARM7 core runs a real-time control loop with sensor read, PID calculation, and PWM update. The 62 KB Flash holds a moderate firmware image.
Integrated ADC and DAC — what the 12-bit resolution buys you
The eight 12-bit ADC channels and four 12-bit DAC outputs are the distinguishing feature of the MicroConverter line.
32-LFCSP package — layout and thermal considerations
The 12 available GPIOs are the count after the ADC and DAC pins are allocated; verify that the I/O budget covers your SPI/I²C bus plus any digital handshake lines before committing the footprint.
