Flash in-system programmable (ISP)

peripherals for 8-bit MCUs, 5 V

Features

■ Flash in-system programmable (ISP)

peripheral for 8-bit MCUs

■ Dual bank Flash memories

PQFP52 (M)

– Up to 2 Mbit of primary Flash memory (8

uniform sectors, 32K x8)

– Up to 256 Kbit secondary Flash memory (4

uniform sectors)

– Concurrent operation: read from one

memory while erasing and writing the other

■ Up to 256 Kbit SRAM

■ 27 reconfigurable I/Oports

■ Enhanced JTAG serial port

PLCC52 (J)

■ 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

TQFP64 (U)

■ 27 individually configurable I/O port pins

■ Programmable power management

They can be used for the following functions:

– MCU I/Os

■ Packages are ECOPACK

– PLD I/Os

– Latched MCU address output

– Special function I/Os.

Table 1.

Device summary
