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. In-System Programming (ISP) via JTAG An IEEE 1149.1 compliant JTAG interface is included on the PSD enabling the entire device (Flash memory, EEPROM, the PLD, and all configuration) to be rapidly programmed while soldered to the circuit board. This requires no MCU participation, which means the PSD can be programmed anytime, even while completely blank.
The innovative JTAG interface to Flash memories is an industry first, solving key problems faced by designers and manufacturing houses, such as: First time programming. How do I get firmware into the Flash the very first time? JTAG is the answer, program the PSD while blank with no MCU involvement. Inventory build-up of pre-programmed devices. How do I maintain an accurate count of preprogrammed Flash memory and PLD devices based on customer demand? How many and what version? JTAG is the answer, build your hardware with blank PSDs soldered directly to the board and then custom program just before they are shipped to customer. No more labels on chips and no more wasted inventory.
Expensive sockets. How do I eliminate the need for expensive and unreliable sockets? JTAG is the answer. Solder the PSD directly to the circuit board. Program first time and subsequent times with JTAG. No need to handle devices and bend the fragile leads.
Applications:
â– 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
â– 16 Kbit SRAM (BATTERY-BACKED)
â– 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)
â– 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.
â– ENHANCED JTAG SERIAL PORT
– Built-in JTAG-compliant serial port allows full-chip In-System Programmability (ISP)
