概述

Description

Introduction (concise)
JS28F128P33TF70A is a 128‑Mbit (16 MB) NOR flash memory in a 28‑pin package, designed for embedded systems. It typically operates at 3.3 V with an access time around 70 ns and uses a parallel NOR interface. It stores firmware, boot code, and non‑volatile data and supports standard NOR operations: read, program, and erase (sectors/blocks). Endurance and sector sizes vary by revision; consult the exact datasheet for details like erase block size, number of sectors, and protection options.
Key specs (typical)
- Capacity: 128 Mbit (16 MB)
- Interface: parallel NOR (D0–D7, A0–A22), control pins (CE, OE, WE, WP)
- Supply: 3.3 V
- Access time: ~70 ns
- Operations: read, program, erase (sector/block)
- Packaging: 28-pin
Note
Variants can differ in timing, block sizes, and protection features. Always verify with the manufacturer’s datasheet for the specific lot/revision before design-in.

Features
