Product details
Overview
AT29LV010A-20JC from Atmel is a 1-Mbit (128K × 8) 3.3V-only Flash memory IC used for in-system firmware storage and boot code retention in embedded controllers. It features 120 ns read access time, 20 ms sector program cycle time, 10,000 write/erase endurance, software data protection, and dual 8K-byte boot blocks with independent programming lockout - deployed in industrial control panels requiring field-upgradable firmware.
For engineers reviewing the AT29LV010A-20JC datasheet, AT29LV010A-20JC pinout, AT29LV010A-20JC application, or AT29LV010A-20JC equivalent, key selection criteria include 3.3V-only operation, PLCC-32 package compatibility, sector-based reprogramming without high-voltage inputs, DATA polling/Toggle Bit status detection, and boot block lockout for secure bootloader protection.
Technical Context
The AT29LV010A-20JC implements a sector-erase architecture with 1024 × 128-byte sectors and internal latching of full-sector data at microprocessor speed. Its software-controlled programming uses a three-byte command sequence (5555h/2AAAh/5555h) followed by byte loads, with automatic erase-before-program and internal timer control.
It supports both hardware and software product identification (Manufacturer Code 1Fh, Device Code 35h), DATA polling on I/O7 and Toggle Bit detection on I/O6 for end-of-program verification, and dual boot block lockout activated via a seven-command algorithm - all operating within 3.3V ± 0.3V supply across commercial temperature range (0°C to 70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8 bits) - sufficient for full BIOS or microcontroller boot image storage |
| Read Access Time | 200 ns - defines maximum clock rate for direct bus interface in 8-bit microcontroller systems |
| Sector Program Time | 20 ms per 128-byte sector - determines firmware update latency during field reprogramming |
| Endurance | >10,000 program/erase cycles per sector - enables multi-year field firmware revision cycles |
| Supply Voltage | 3.3 V ± 0.3 V - eliminates need for charge pumps or external 12V programming voltage |
| Standby Current | 40 µA (CMOS) - critical for low-power battery-backed systems during sleep mode |
| Operating Temperature | 0°C to 70°C - validated for commercial-grade industrial human-machine interfaces (HMIs) |
Pinout & Package
AT29LV010A-20JC is housed in a 32-lead Plastic Leaded Chip Carrier (PLCC) package with J-bend leads, JEDEC MS-016 compliant, body size 12.45 mm × 12.45 mm × 3.35 mm (max height), lead coplanarity ≤0.102 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-byte addressing; A7–A16 select sector, A0–A6 select byte within sector |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface compatible with 8-bit microcontrollers; supports DATA polling on I/O7 and Toggle Bit on I/O6 |
| CE | Chip Enable | Active-low chip select; when high, places outputs in high-impedance state to prevent bus contention |
| OE | Output Enable | Active-low read control; must be high during programming to inhibit output drivers |
| WE | Write Enable | Active-low programming control; used with CE to latch addresses/data during sector load cycles |
| VCC | Power Supply | 3.3V ± 0.3V main supply; internal VCC sense disables programming if voltage drops below 1.8V |
| GND | Ground | Reference for all input thresholds and output levels; decoupling required near VCC pin |
| NC | No Connect | Two unconnected pins (PLCC pins 13 & 31); must remain floating - no external connection permitted |
Key Features
| Feature | Design Value |
|---|---|
| 3.3V-only programming | Eliminates need for external 12V programming supply - simplifies PCB layout and reduces BOM count |
| Software data protection | Three-byte unlock sequence prevents accidental writes during power transitions or noise events |
| Dual boot block lockout | Independent 8K-byte lockable regions at 0x0000–0x1FFF and 0xE000–0xFFFF - secures bootloader against corruption |
| DATA polling & Toggle Bit | Real-time program completion detection without external timers - enables deterministic firmware update sequencing |
| Internal address/data latching | Full 128-byte sector captured at microprocessor speed - frees system bus for concurrent operations during programming |
| CMOS/TTL-compatible I/O | Input thresholds (VIL = 0.6V, VIH = 2.0V) and output drive (IOH = –100 µA, IOL = 1.6 mA) ensure interoperability with legacy 5V logic |
Applications
| Industrial HMI Firmware Storage | Legacy PLC Boot Memory |
|---|---|
Use Scenario: Storing updatable firmware and configuration data in panel-mounted human-machine interface terminals exposed to factory floor vibration and temperature cycling. IC Role / Device Role / Timing Role: Nonvolatile boot memory holding startup code and UI assets; accessed at power-on reset and during over-the-air updates. Use Value: 20 ms sector programming enables <100 ms firmware patching; 10,000-cycle endurance supports 5+ years of quarterly updates without replacement. |
Use Scenario: Retaining boot code and ladder logic runtime in programmable logic controllers using 8-bit microcontrollers with limited external memory buses.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT29BV010A-20JC | Successor with improved reliability, same pinout and timing; rated for 100,000 cycles vs. 10,000 | Drop-in replacement for new designs; identical boot block lockout and software protection | Select for new designs requiring extended lifecycle and higher endurance |
| SST39VF010-20-4C-NHE | 3.3V Flash with 200 ns access, 100,000-cycle endurance, but lacks boot block lockout and uses different command set | Requires firmware driver modification; no hardware-protected boot region | Choose only when boot block security is not required and driver porting effort is acceptable |
Compared with AT29LV010A-20JC, AT29BV010A-20JC offers 10× higher endurance and identical footprint for seamless migration, while SST39VF010 requires software adaptation due to incompatible command protocols and absence of lockout features - making AT29BV010A the preferred upgrade path.

FAQ
What is the maximum operating temperature range for the AT29LV010A-20JC?
The AT29LV010A-20JC is specified for commercial temperature operation from 0°C to 70°C. It is not rated for industrial temperature range (–40°C to +85°C); for that, the AT29LV010A-20JI variant must be selected. This distinction is critical for thermal design validation in enclosed enclosures without active cooling.
Does the AT29LV010A-20JC require external high-voltage programming signals?
No, the AT29LV010A-20JC operates with 3.3V-only programming - no external 12V or 5V programming voltage is needed. All commands, including sector erase and byte programming, are executed using standard 3.3V logic levels and a defined three-byte unlock sequence, simplifying system-level power design.
How does the boot block lockout feature work on the AT29LV010A-20JC?
The AT29LV010A-20JC provides two independent 8K-byte boot blocks (lower: 0x0000–0x1FFF; upper: 0xE000–0xFFFF) that can be permanently locked via a seven-command software algorithm. Once enabled, those regions become read-only - preventing accidental erasure of bootloader code during field firmware updates.
Can the AT29LV010A-20JC be used with 5V microcontrollers?
Yes - the AT29LV010A-20JC has CMOS/TTL-compatible inputs and outputs. Its input thresholds (VIL = 0.6V, VIH = 2.0V) accept 5V logic levels, and outputs drive to 2.4V (IOH = –100 µA) and 0.45V (IOL = 1.6 mA) at 3.0V VCC, enabling safe interfacing with 5V systems without level shifters.
What methods are available to detect program completion on the AT29LV010A-20JC?
The AT29LV010A-20JC supports two hardware-verified methods: DATA polling on I/O7 (complement-to-data during programming, true data upon completion) and Toggle Bit detection on I/O6 (toggling during operation, steady state upon completion). Both allow real-time, interrupt-driven status monitoring without fixed delays.
