Product details
Overview
AM29F002BT-55JF from Spansion (originally AMD) is a 2 Mbit (256 K × 8-bit) 5.0 V-only boot sector Flash memory with 55 ns access time, top-boot sector architecture, and hardware RESET# pin. It supports in-system programming via standard 5 V VCC-no VPP required-and delivers 1 µA standby current, 20 mA read current, and embedded erase/program algorithms for reliable firmware storage in microcontroller boot applications.
For engineers reviewing the AM29F002BT-55JF datasheet, AM29F002BT-55JF pinout, AM29F002BT-55JF application, or AM29F002BT-55JF equivalent, this page provides verified technical context, sector protection behavior, Erase Suspend capability, TSOP-32 package mapping, and JEDEC command-set compatibility-critical for legacy industrial controller and BIOS firmware replacement designs.
Technical Context
The AM29F002BT-55JF implements a flexible boot-sector Flash architecture with one 16 KB, two 8 KB, one 32 KB, and three 64 KB sectors-enabling selective erasure without disturbing boot code. Its embedded Erase and Program algorithms auto-verify cell margin and manage pulse timing internally.
It features Data# Polling (DQ7) and Toggle Bits (DQ6/DQ2) for software status detection, Erase Suspend/Erase Resume for background operations, and hardware RESET# to force immediate return to read mode-distinct from the NB variant which omits RESET#.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Mbit (262,144 × 8-bit), organized as 256 Kbytes for direct byte-addressable firmware storage |
| Access Time (tACC) | 55 ns-enables zero-wait-state operation with 18 MHz microprocessors |
| Supply Voltage | 5.0 V ± 5%-single-supply operation eliminates need for VPP or charge pumps |
| Standby Current | 1 µA typical at 5 MHz-reduces power in idle states for battery-backed systems |
| Endurance | 1,000,000 program/erase cycles per sector-supports field firmware updates over product lifetime |
| Data Retention | 20 years at 125°C-ensures long-term reliability in automotive and industrial thermal environments |
| Sector Architecture | Top-boot configuration: 16 KB + 2×8 KB + 32 KB + 3×64 KB-protects critical boot code in uppermost sector |
Pinout & Package
AM29F002BT-55JF is housed in a 32-pin Thin Small Outline Package (TSOP) with gull-wing leads, compliant with JEDEC MO-142AA. Pin 1 is index-marked; pins A0–A17 provide 18 address lines, DQ0–DQ7 serve as bidirectional data I/O, and dedicated control signals (CE#, OE#, WE#, RESET#) enable precise bus arbitration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256 KB addressing; A0 = LSB, A17 = MSB |
| DQ0–DQ7 | Data Input/Output | 8-bit bidirectional data path; latched during write, tri-stated when OE# and CE# inactive |
| CE# | Chip Enable (active low) | Primary device selection signal; must be asserted before OE# or WE# for valid operation |
| OE# | Output Enable (active low) | Controls output buffer; allows data read without toggling CE# during burst reads |
| WE# | Write Enable (active low) | Controls write latching; used with CE# and OE# to define bus cycle type (read/write) |
| RESET# | Hardware Reset (active low) | Aborts any ongoing erase/program operation and forces device into read array mode immediately |
| VCC | Power Supply | +5.0 V ± 5% supply powering all internal logic, charge pumps, and I/O buffers |
| VSS | Ground | Reference ground for all signals and internal circuitry; requires low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Embedded Erase Algorithm | Automatically pre-programs and verifies entire chip or selected sectors-eliminates external timing control |
| Erase Suspend/Erase Resume | Pauses active erase to read/program non-target sectors-enables real-time firmware patching during background erase |
| Hardware Sector Protection | Locks individual sectors via programming equipment to prevent accidental writes-no software dependency |
| Temporary Sector Unprotect | Allows runtime unlocking of previously protected sectors using command sequence-enables secure update windows |
| Low VCC Write Inhibit | Internally disables write operations below ~3.5 V-prevents corruption during brown-out or power ramp-up |
Applications
| Industrial PLC Firmware Storage | Legacy PC BIOS Memory |
|---|---|
|
Use Scenario: Storing boot firmware and configuration data in programmable logic controllers operating in wide-temperature industrial enclosures. IC Role / Device Role / Timing Role: Non-volatile boot memory mapped to CPU reset vector; provides deterministic startup within 55 ns access window. Use Value: Top-boot sector architecture isolates reset vector in protected 16 KB block; 20-year data retention ensures firmware integrity across 15+ year deployments. |
Use Scenario: Replacing obsolete EPROMs in legacy desktop motherboard BIOS chips requiring in-circuit reprogramming. IC Role / Device Role / Timing Role: Direct drop-in replacement for 27C020 EPROMs; JEDEC-compatible command set enables reuse of existing BIOS update utilities. Use Value: No VPP requirement simplifies board redesign; RESET# pin synchronizes system reset with Flash initialization-eliminating boot hangs. |
| Telecom Line Card Boot Loader | Medical Device Configuration Memory |
|
Use Scenario: Holding boot loader and FPGA configuration bitstreams on carrier-grade telecom line cards subject to frequent field upgrades. IC Role / Device Role / Timing Role: Dual-role memory: stores boot code (top sectors) and field-upgradable application images (lower sectors). Use Value: Erase Suspend allows simultaneous diagnostics execution while background sector erase proceeds-minimizing service downtime. |
Use Scenario: Storing calibrated sensor offsets, safety-critical operational parameters, and regulatory compliance flags in Class II medical instruments. IC Role / Device Role / Timing Role: Secure configuration store with hardware sector lock; RESET# ensures known state after power-on reset per IEC 62304. Use Value: 1,000,000-cycle endurance supports >10,000 calibration cycles; 125°C data retention validates long-term stability under sterilization heat exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar boot-sector Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF020-55-4C-NHE | 3.3 V operation, 55 ns access, no RESET# pin, 2 MB density same but sector map differs (eight 256 KB blocks) | Lacks hardware reset and top-boot flexibility; requires voltage translation in 5 V systems | Select only if migrating to 3.3 V design and accepting software-based reset handling |
| MX29F002TC-55G | 5 V operation, 55 ns, includes RESET#, identical sector architecture and JEDEC command set | Pin- and function-compatible replacement; manufactured by Macronix with same AMD-derived IP | Preferred drop-in alternative with full functional equivalence and extended lifecycle support |
Compared with SST39VF020-55-4C-NHE, AM29F002BT-55JF offers native 5 V operation and hardware RESET# for deterministic boot recovery; versus MX29F002TC-55G, it shares identical timing and protection features but reflects original AMD/Spansion qualification history critical for legacy audit trails.

FAQ
Does AM29F002BT-55JF require an external VPP voltage for programming?
No. The device operates with a single 5.0 V ± 5% supply for read, program, and erase functions. Internal charge pumps generate necessary high voltages, eliminating the need for external VPP circuitry or programming adapters-enabling true in-system reprogramming using standard microprocessor buses.
What is the purpose of the RESET# pin, and is it present on all variants?
RESET# is an active-low hardware pin that immediately terminates any ongoing erase or program operation and forces the device back into read array mode. It is present only on the "B" suffix variants (e.g., AM29F002BT-55JF); the "NB" variant omits this pin entirely, relying solely on software reset commands.
How does sector protection work, and can locked sectors be modified in-circuit?
Sector protection is implemented via hardware locking: once a sector is locked using the manufacturer-specified command sequence, no program or erase commands affect it-even if addressed. Temporary Sector Unprotect allows runtime unlocking of a protected sector using a timed command sequence, enabling secure, time-limited firmware updates without full chip erase.
Is AM29F002BT-55JF compatible with standard EPROM programmers?
Yes. The device supports programming in conventional EPROM programmers that comply with JEDEC-standard command sets and 5 V interface levels. Its pinout and software protocol match industry-standard single-power-supply Flash devices, allowing reuse of existing programming infrastructure without adapter hardware.
