µPSD323X
Flash Programmable System Devices
with 8032 Microcontroller Core and 64Kbit SRAM
FEATURES SUMMARY
s
The
µPSD323X
Devices combine a Flash PSD
architecture with an 8032 microcontroller core.
The
µPSD323X
Devices of Flash PSDs feature
dual banks of Flash memory, SRAM, general
purpose I/O and programmable logic, supervi-
sory functions and access via USB, I
2
C, 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
µPSD323X
Devices are also in-system pro-
grammable (ISP) via a JTAG ISP interface.
