FEATURES SUMMARY

■ The uPSD321X Devices combine a Flash PSD architecture with an 8032 microcontroller core. The uPSD321X Devices of Flash PSDs feature d)ual banks of Flash memory, SRAM, general purpose I/O and programmable logic, supervisory functions and access via I2C, ADC 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 uPSD321X Devices are also in-system programmable (ISP) via a JTAG ISP interface.
