PSD4256G6V-10UI Description

Short technical summary and product information.

The PSD4256G6V-10UI from STMicroelectronics is a versatile Flash In-System Programmable (ISP) peripheral IC. It is designed to work with 8-bit or 16-bit microcontrollers, offering a robust solution for embedded systems.

This device features dual-bank Flash memories, including 8 Mbits of primary Flash and 512 Kbits of secondary Flash. It also includes 256 Kbits of SRAM, allowing for concurrent read operations from one memory bank while erasing and writing to the other. The IC supports in-system programming via JTAG, facilitating efficient manufacturing testing and programming.

With a single supply voltage of 3V, the PSD4256G6V-10UI offers memory access times of 100 ns for VCC = 3V and 90 ns for VCC = 3.3V. It provides high endurance for its Flash memory (100,000 erase/write cycles) and PLD (1,000 erase/write cycles), along with 15 years of data retention. The component is housed in an 80-lead Thin Quad Flat Package (LQFP) suitable for surface mounting.

Key features include seven I/O ports with 52 individually configurable I/O pins, programmable power management, and an internal page register for expanding microcontroller address space. The ECOPACK® compliant packaging makes it suitable for environmentally conscious designs.
