Description

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.
  
FEATURES SUMMARY
■ 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 BATTERY-BACKED SRAM
■ 27 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
■ 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
■ PROGRAMMABLE POWER MANAGEMENT
■ HIGH ENDURANCE:
    – 100,000 Erase/WRITE Cycles of Flash  Memory
    – 1,000 Erase/WRITE Cycles of PLD
    – 15 Year Data Retention
■ 5V±10% SINGLE SUPPLY VOLTAGE
■ STANDBY CURRENT AS LOW AS 50µA
