controller 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.

cation Programming (IAP) for remote updates
– Large 64KByte main Flash memory for appli-
cation code, operating systems, or bit maps
for graphic user interfaces
– Large 16KByte secondary Flash memory di-
vided in small sectors. Eliminate external EE-
PROM with software EEPROM emulation
– Secondary Flash memory is large enough for

es, communication buffers, and stacks
s Programmable Decode PLD for flexible address
mapping of all memories
– Place individual Flash and SRAM sectors on
any address boundary
– Built-in page register breaks restrictive 8032
limit of 64KByte address space

ments between 8032 “program” space and
“data” space for efficient In-Application Pro-
gramming

s In-System Programming (ISP) via JTAG
– Program entire chip in 10 - 25 seconds with
no involvement of 8032
– Allows efficient manufacturing, easy product
testing, and Just-In-Time inventory
– Eliminate sockets and pre-programmed parts
– Program with FlashLINKTM cable and any PC
s Content Security
– Programmable Security Bit blocks access of
device programmers and readers
s Zero-Power Technology
– Memories and PLD automatically reach
standby current between input changes
