■ 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

■ 27 INDIVIDUALLY CONFIGURABLE I/O

PORT PINS

The can be used for the following functions:

– MCU I/Os

– PLD I/Os

– Latched MCU address output

– Special function I/Os.

– 16 of the 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
