概要

Description

PC28F512P33TFA is a 512‑Mbit parallel NOR flash memory device (store firmware/nonvolatile code) designed for embedded systems. Key points:
- Density: 512 Mbit (64 MB)
- Interface: 8‑bit data bus (parallel NOR), with standard NOR flash signals (CE, OE, WE) for asynchronous operation
- Supply: 3.3 V operation
- Operations: random reads, byte/word programming, and block/sector erase via a conventional flash command set
- Features: nonvolatile storage for firmware and boot code, with typical protection options and block erase Granularity
- Packaging: standard packaging denoted by the TFA suffix (e.g., TSOP/CFI-compatible package)
Common use cases include storing microcontroller/processor firmware, BIOS-like boot code, and other nonvolatile code/images that must be reliably read quickly at runtime.

Features

Here are the typical features of PC28F512P33TFA (a 3.3V, parallel NOR flash):
- 3.3V single-supply operation; 8-bit I/O
- Density: 512 Kbit (64K × 8)
- Random access read; supports byte/word programming
- Block/sector erase capability (standard NOR flash erase)
- In-system/at-socket programming via standard command set
- Endurance: around 100,000 program/erase cycles per sector
- Data retention: typically >10–20 years
- Protection features: hardware write protection (WP) and software protection mechanisms
- Power management: sleep/standby and/or deep-power-down modes
- Fast read access times (typical NOR read times; exact ns depends on device variant)
- Operating temperature range suitable for industrial use (commonly -40°C to +85°C)
- Package options: 32-pin (and related variants) parallel flash packages
Note: exact timing, block sizes, and packaging can vary by revision; consult the official datasheet for precise figures.

Package

32-pin TSOP (Thin Small Outline Package).

Pinout

- Pin count: 28 pins
- Function: 3.3V parallel NOR flash memory (512 kbit, 8-bit I/O). Provides address inputs (A0–A15), data I/O lines (DQ0–DQ7), and standard flash controls (chip select/enable, output enable, write enable), plus Vcc and GND.

Manufacturer

- Manufacturer: Spansion Inc.
- What kind of company: A semiconductor company that specialized in non-volatile memory (NOR/NAND flash) and embedded memory solutions; originally a joint venture of AMD and Fujitsu, later acquired by Cypress Semiconductor (now part of Infineon).
