JS28F128P30T85A

The Numonyx JS28F128P30T85A is a 128Mbit embedded memory device from the StrataFlash P30 family, utilizing Multi-Level Cell Technology for high density at a low cost. It features an asymmetrically-blocked architecture with four 32-KByte parameter blocks and 128-KByte main blocks.

This NOR Flash memory provides high performance with an initial access time of 85 ns and a 25 ns asynchronous-page read mode. It supports synchronous-burst read mode at 52 MHz with zero wait states and a 17ns clock-to-data output. The device operates with a core voltage (VCC) between 1.7 V and 2.0 V, and an I/O voltage (VCCQ) between 1.7 V and 3.6 V.

Designed for industrial applications, the JS28F128P30T85A operates reliably in temperatures ranging from -40 °C to +85 °C. It is available in a 56-lead TSOP package, suitable for surface mounting on PCBs. The memory offers features like buffered enhanced factory programming and buffered programming at 1.8V, with program and erase suspend times of 20 μs typical.

Security features include one-time programmable registers for device identification and user-programmable bits. It also supports absolute write protection and power-transition lockout for enhanced data integrity. The memory has a minimum of 100,000 erase cycles per block, ensuring long-term reliability.
