The uPSD323X Devices combine a Flash PSD architecture with an 8032 microcontroller core. The uPSD323X Devices of Flash PSDs feature dual banks of Flash memory, SRAM, general purpose I/O and programmable logic, supervisory functions and access via USB, I²C, ADC, DDC and PWM channels, and an on-board 8032 microcontroller core, with two UARTs, three 16-bit Timer/Counters and two External Interrupts. As with other Flash PSD families, the uPSD323X Devices are also in-system programmable (ISP) via a JTAG ISP interface.
