概述

Description

PC28F640P30BF65A is a parallel NOR flash memory device (non-volatile) used to store firmware or other code/data in embedded systems. Key points:
- Capacity: 64 Mbit (8 MB) of storage.
- Interface: Parallel address/data interface (not SPI).
- Typical organization and operation: random read; block/sector erase with 64 KB blocks; page program around a few hundred bytes (commonly 256 bytes).
- Voltage and timing: variants exist; many NOR parts run on low-voltage supplies (e.g., 3.0–3.3 V) or 5 V, with access times in tens to a few hundred nanoseconds depending on speed grade.
- Marking BF65A is a lot code/date code; exact electrical characteristics depend on the specific fabricator and revision.
For precise specs (voltage range, timings, block/page sizes, package, and recommended operating conditions), consult the exact vendor datasheet for PC28F640P30BF65A. If you know the manufacturer (Spansion/Winbond/others), I can point to the correct datasheet.

Features

Here are the key features of PC28F640P30BF65A (NOR flash):
- Density: 64 Mbit (8 MByte)
- Interface: Parallel NOR flash, x8 data bus
- Voltage: 2.7–3.6V (3V family)
- Access time: ~30 ns
- Read: random read capability
- Write/Erase: supports byte/word program and block/sector erase

Note: Refer to the official datasheet for exact block sizes, timings, and operating conditions.

Package

TSOP-48 (Plastic Small-Outline) package.

Pinout

Pin count: 48 pins.
Function: PC28F640P30BF65A is a 64‑Mbit parallel NOR flash memory (3.0V operation) used for non-volatile firmware storage. It provides random read access and sector/block erase/program via an 8-bit data bus (x8).

Manufacturer

Manufacturer: Spansion. Spansion is a semiconductor company that designs and manufactures flash memory (NOR/NAND) chips; originally a joint venture of AMD and Fujitsu, later acquired by Cypress Semiconductor (now part of Infineon).

Application

PC28F640P30BF65A is a NOR flash memory (64 Mbit) for non-volatile code and data storage in embedded systems. Common applications:
- BIOS/firmware storage and execute-in-place (XIP)
- Boot ROM for microcontrollers
- Industrial/process-control systems
- Automotive ECUs and infotainment
- Consumer electronics (set-top boxes, cameras, printers, media players)
- Networking equipment (routers, switches)
- Other embedded products needing fast random access and reliable nonvolatile storage

Equivalent

Possible equivalents (64-Mbit, 8-bit parallel NOR flash, 3.3V, ~30 ns) include:
- AMD AM28F640J
- Spansion/Cypress S29GL064M (and related variants)
Note: verify exact package/pinout, timing, and cross-reference table for your design.
