Summary description

The PSD8XXFX family of memory systems for microcontrollers (MCUs) brings in-system-programmability (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.

特性 Features

■ Flash in-system programmable (ISP) peripheral for 8-bit MCUs

■ Dual bank Flash memories

– 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

■ 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

They 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

■ Programmable power management

■ Packages are ECOPACK?
