Summary description

The PSD8XXFX family of memory systems for microcontrollers (MCUs) brings in-systemprogrammability (ISP) to Flash memory and programmable logic. The result is a simple and flexible solution for embedded designs. PSD devices combine many of the peripheral functions found in MCU based applications.

Features

¡ö Flash in-system programmable (ISP)

peripheral for 8-bit MCUs

¡ö Dual bank Flash memories

¨C Up to 2 Mbit of primary Flash memory (8

uniform sectors, 32K x8)

¨C Up to 256 Kbit secondary Flash memory (4

uniform sectors)

¨C Concurrent operation: read from one

memory while erasing and writing the other

¡ö Up to 256 Kbit SRAM

¡ö 27 reconfigurable I/Oports

¡ö Enhanced JTAG serial port

¡ö PLD with macrocells

¨C Over 3000 gates of PLD: CPLD and DPLD

¨C CPLD with 16 output macrocells (OMCs)

and 24 input macrocells (IMCs)

¨C DPLD - user defined internal chip select

decoding

¡ö 27 individually configurable I/O port pins

They can be used for the following functions:

¨C MCU I/Os

¨C PLD I/Os

¨C Latched MCU address output

¨C Special function I/Os.

¨C 16 of the I/O ports may be configured as

open-drain outputs.

¡ö In-system programming (ISP) with JTAG

¨C Built-in JTAG compliant serial port allows

full-chip in-system programmability

¨C Efficient manufacturing allow easy product

testing and programming

¨C Use low cost FlashLINK cable with PC

¡ö Page register

¨C Internal page register that can be used to

expand the microcontroller address space

by a factor of 256

¡ö Programmable power management

¡ö Packages are ECOPACK?
