PSD934F2-90JI(PSD934F2-90J) - Brand New STMicroelectronics IC Chips
-
Description
The PSD934F2-90JI (PSD934F2-90J) is an electronic component model in the IC Chips product category. It belongs to the PSD8XXFX family of memory systems for microcontrollers (MCUs) that brings In-System-Programmability (ISP) to Flash memory and programmable logic. This model offers a simple and flexible solution for embedded designs, combining many of the peripheral functions found in MCU-based applications.
Specifications and features
- FLASH IN-SYSTEM PROGRAMMABLE (ISP) peripheral for 8-bit MCUs - Dual bank flash memories with up to 2 Mbit of primary flash memory (8 uniform sectors, 32K x8) and 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) - 27 individually configurable I/O port pins for various functions such as MCU I/Os, PLD I/Os, latched MCU address output, special function I/Os, and open-drain outputs (16 of the I/O ports can be configured as open-drain outputs) - In-system programming (ISP) with JTAG for full-chip in-system programmability - Built-in JTAG compliant serial port allows for efficient manufacturing, easy product testing, and programming (can use a low-cost FlashLINK cable with PC) - Page register for expanding the microcontroller address space by a factor of 256 - Programmable power management - High endurance with 100,000 erase/write cycles of flash memory, 1,000 erase/write cycles of PLD, and 15-year data retention - 5V±10% single supply voltage - Standby current as low as 50µA
Application Scenarios
The PSD934F2-90JI (PSD934F2-90J) can be widely used in various embedded designs requiring memory systems for microcontrollers. Its features and flexibility make it suitable for MCU-based applications that require in-system programmability, flash memory, programmable logic, and reconfigurable I/O ports. It can be utilized in industries such as electronics, telecommunications, automotive, industrial automation, and consumer electronics.
Comparison
