Flash In-System Programmable (ISP) Peripherals for 8-bit MCUs, 5V

Description:

The PSD family of Programmable Microcontroller

(MCU) Peripherals 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.

PSD devices integrate an optimized “microcontroller macrocell” logic architecture. The Macrocell was created to address the unique requirements of embedded system designs. It allows direct connection between the system address/data bus and the internal PSD registers to simplify communication between the MCU and other supporting devices.

The PSD family offers two methods to program PSD Flash memory while the PSD is soldered to a circuit board.

Applications:

■ DUAL BANK FLASH MEMORIES

– 1 Mbit of Primary Flash Memory (8

Uniform Sectors)

– 256 Kbit Secondary EEPROM (4 Uniform

Sectors)

– Concurrent operation: read from one

memory while erasing and writing the

other

■ 16 Kbit SRAM (BATTERY-BACKED)

■ PLD WITH MACROCELLS

– Over 3,000 Gates Of PLD: DPLD and

CPLD

– DPLD - User-defined Internal chip-select

decoding

– CPLD with 16 Output Macrocells (OMCs)

and 24 Input Macrocells (IMCs)

■ 27 RECONFIGURABLE I/Os

– 27 individually configurable I/O port pins

that can be used for the following

functions:

MCU I/Os;

PLD I/Os;

Latched MCU address output; and

Special function I/Os.

Note: 16 of the I/O ports may be

configured as open-drain outputs.

■ ENHANCED JTAG SERIAL PORT

– Built-in JTAG-compliant serial port allows

full-chip In-System Programmability (ISP)

– Efficient manufacturing allows for easy

product testing and programming

■ 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

– 10,000 Erase/WRITE Cycles of EEPROM

– 1,000 Erase/WRITE Cycles of PLD

– Data Retention: 15-year minimum at 90°C

(for Main Flash, Boot, PLD and

Configuration bits).

■ SINGLE SUPPLY VOLTAGE:

– 5V±10% for 5V

■ STANDBY CURRENT AS LOW AS 50µA
