Overview

Description

The JS28F512P33BFD is a parallel (NOR) flash memory device commonly used to store firmware and data in embedded systems. It provides non-volatile, random-access storage with a capacity of 512 megabits (64 MB). It typically operates from a 3.3 V single supply (the P33 in the name hints at 3.3 V). The device uses a parallel data bus (x8 or x16) and supports standard NOR flash operations: Read, Page Program, and Block Erase, with status reporting and typical timing specs in the datasheet.
Key points:
- Type: NOR flash (parallel interface) for random access and execute-in-place (XIP) in some designs.
- Capacity: 512 Mbit (64 MB).
- Voltage: 3.3 V nominal.
- Common usage: firmware boot code, parameter storage, and code updates in microcontroller-based systems.
- Package/variant: BFD likely indicates RoHS-compliant package; P33 confirms 3.3 V operation.
For exact timing, sector/page sizes, command set, endurance, and packaging, refer to the manufacturer’s datasheet.
