memory while erasing and writing the
other
64 KBIT OF BATTERY-BACKED SRAM
52 RECONFIGURABLE I/O PORTS
ENHANCED JTAG SERIAL PORT
PLD WITH MACROCELLS
– Over 3000 Gates of PLD: CPLD and
DPLD
– CPLD with 16 Output Macrocells (OMCs)
and 24 Input Macrocells (IMCs)
– DPLD - user defined internal chip select
decoding
52 INDIVIDUALLY CONFIGURABLE I/O
PORT PINS
They can be used for the following functions:
– MCU I/Os
– PLD I/Os
– Latched MCU address output
– Special function I/Os.
– I/O ports may be configured as open-drain
outputs.
IN-SYSTEM PROGRAMMING (ISP) WITH
JTAG
– Built-in JTAG compliant serial port allows
full-chip In-System Programmability
– Efficient manufacturing allow easy
product testing and programming
– Use low cost FlashLINK cable with PC
PAGE REGISTER
– Internal page register that can be used to
expand the microcontroller address space
by a factor of 256
