PSD4235G2V-90U Description

Short technical summary and product information.

The STMicroelectronics PSD4235G2V-90U is a Flash in-system programmable (ISP) memory device designed for 16-bit MCUs. It features dual-bank Flash memories with 4 Mbit of primary Flash and 256 Kbit of secondary Flash, alongside 64 Kbit of SRAM.

 

Key electrical specifications include a single supply voltage of 5V ± 10% and memory access times of 70ns for both Flash and SRAM. The device offers high endurance with 100,000 erase/write cycles for Flash memory and 1,000 cycles for PLD. Data retention is rated for 15 years.

 

This IC includes PLD functionality with over 3000 gates, CPLD with 16 output macrocells, and DPLD. It provides 7 I/O ports with 52 individually configurable I/O pins. The device supports in-system programming (ISP) via JTAG and features an internal page register for expanding the microcontroller address space.

 

The PSD4235G2V-90U is supplied in an 80-lead Thin Quad Flat Package (LQFP) suitable for surface mounting.
