FEATURES SUMMARY
September 2003
Rev. 1.2
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, supervi-
sory functions and access via USB, I
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 pro-
grammable (ISP) via a JTAG ISP interface.
Large 8KByte SRAM with battery back-up
option
Dual bank Flash memories
– 128KByte or 256KByte main Flash memory
– 32KByte secondary Flash memory
Content Security
– Block access to Flash memory
Programmable Decode PLD for flexible address
mapping of all memories within 8032 space.
High-speed clock standard 8032 core (12-cycle)
USB Interface (some devices only)
