PRELIMINARY DATA
FEATURES SUMMARY
PSD provides an integrated solution to 16-bit
MCU-based applications that includes config-
urable memories, PLD logic, and I/O:
s
Dual bank Flash memories
– 8Mbits of Primary Flash Memory (16 uniform
sectors, 64Kbyte)
– 512Kbits of Secondary Flash Memory with 4
sectors
– Concurrent operation: READ from one mem-
ory while erasing and writing the other
