Puya Semiconductor Serial NOR Flash PY25Q32HB-SSH-IR - ME-3841-D

The Puya Semiconductor PY25Q32HB-SSH-IR is a non-volatile Serial NOR Flash memory designed for firmware, program code, and data storage in embedded electronic systems. It provides 32 Mbit (4 MB) of memory and supports Single, Dual, and Quad SPI as well as QPI communication modes.

The device supports clock frequencies up to 133 MHz and offers 256-byte page programming, 4-KB sector erase, and 32-KB/64-KB block erase. It also includes hardware write protection, OTP security registers, and a 128-bit unique device ID. The SSH-IR ordering code is rated for operation from -40°C to +85°C, with 100,000 program/erase cycles and up to 20 years of data retention. <Cite refs={["turn912662search0","turn912662search12","turn912662search13"]}/>
