Product details
Overview
AT29LV010A-15JC from Atmel is a 1 Mbit (128K × 8) 3.3 V-only Flash memory IC organized as 131,072 bytes × 8 bits, featuring 120 ns read access time, 20 ms sector program cycle time, and software-controlled sector erase/program with 1024 × 128-byte sectors. It supports boot block lockout for secure firmware storage in embedded microcontroller systems.
For engineers reviewing the AT29LV010A-15JC datasheet, AT29LV010A-15JC pinout, AT29LV010A-15JC application, or AT29LV010A-15JC equivalent, key selection considerations include 3.3 V-only operation, sector-level reprogrammability, DATA polling/toggle-bit programming status detection, and PLCC-32 packaging for legacy board compatibility.
Technical Context
The AT29LV010A-15JC implements a sector-erase architecture with internal address/data latching for 128-byte loads, eliminating external bus hold requirements during programming. Its software data protection uses a three-byte command sequence (AAh→55h→A0h) to enable sector writes, preventing inadvertent modification.
It features dual 8 KB boot blocks with independent lockout activation via a seven-command algorithm, and supports hardware-based protection including VCC sense (<1.8 V inhibit), noise filtering (<15 ns pulse rejection), and CE/OE/WE control-state inhibition - all operating within 3.3 V ±0.3 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8 bits) - supports full firmware image storage for 8-bit microcontrollers |
| Read Access Time | 150 ns max - meets timing for 6–7 MHz bus interfaces without wait states |
| Sector Program Time | 20 ms typical - enables rapid field updates of 128-byte firmware segments |
| Supply Voltage | 3.3 V ±0.3 V - compatible with modern low-voltage logic and eliminates need for 5 V or 12 V programming rails |
| Endurance | >10,000 write/erase cycles per sector - suitable for infrequent configuration or calibration data updates |
| Standby Current | 40 µA (commercial) / 50 µA (industrial) - enables low-power retention in battery-backed systems |

Pinout & Package
AT29LV010A-15JC is packaged in a 32-lead Plastic Leaded Chip Carrier (PLCC), JEDEC MS-016 compliant, with 1.27 mm pitch and body dimensions 12.45 mm × 14.95 mm. Pin 1 identifier is a corner notch on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 131,072-byte addressing; A7–A16 select sector, A0–A6 select byte within sector |
| CE | Chip Enable | Active-low chip select; must be low for read/write; high forces outputs to high-impedance state |
| OE | Output Enable | Active-low output control; used with CE to manage bus contention during reads |
| WE | Write Enable | Active-low write strobe; initiates byte load and sector programming when CE is low and OE is high |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit multiplexed data path for both read output and program input; supports CMOS/TTL voltage levels |
| VCC | Power Supply | 3.3 V ±0.3 V main supply; internal regulation ensures stable core operation across voltage tolerance |
| GND | Ground Reference | Signal and power return; decoupling capacitor required at VCC pin per layout guidelines |
| NC | No Connect | Two unconnected pins (PLCC pins 13 and 31); must remain floating - no external connection permitted |
Key Features
| Feature | Design Value |
|---|---|
| Software Data Protection | Three-byte unlock sequence (5555h→2AAAh→5555h) required before any sector write - prevents accidental firmware corruption during power-up or noise events |
| Boot Block Lockout | Independent 8 KB upper/lower block lock via 7-command algorithm - secures bootloader code against overwrite while allowing application partition updates |
| DATA Polling & Toggle Bit | I/O7 complement-read and I/O6 toggle provide real-time, bus-compatible programming status feedback - eliminates need for fixed delay timers in host firmware |
| Internal Address/Data Latching | 128-byte sector data captured at microprocessor speed and held internally - frees address/data bus for concurrent operations during 20 ms program cycle |
| CMOS/TTL Compatibility | Inputs accept 0–5.5 V; outputs drive to 0.45 V low / 2.4 V high at 3.0 V VCC - interoperable with mixed-voltage 3.3 V/5 V system designs |

FAQ
What is the maximum read access time specified for AT29LV010A-15JC?
The AT29LV010A-15JC has a maximum read access time of 150 ns under commercial temperature conditions (0°C to 70°C) at 3.3 V supply. This value is guaranteed across the full operating voltage range (3.0 V to 3.6 V) and defines the minimum time between address valid and stable data output on I/O0–I/O7. The "-15" suffix explicitly denotes this 150 ns timing grade, distinguishing it from faster (-12, 120 ns) or slower (-20, 200 ns) variants of the same device family.
Does AT29LV010A-15JC require high-voltage programming signals?
No, AT29LV010A-15JC operates exclusively at 3.3 V for both read and write functions - no 5 V, 12 V, or other elevated programming voltages are needed. Programming is enabled solely through a software command sequence applied to the standard address and data bus, with internal circuitry generating necessary voltage levels. This eliminates external high-voltage generators and simplifies system design, making AT29LV010A-15JC suitable for in-circuit reprogramming without special hardware.
How many sectors does AT29LV010A-15JC have, and what is the size of each sector?
AT29LV010A-15JC contains 1024 uniform sectors, each sized at 128 bytes. This structure enables granular firmware updates - only the modified sector needs erasure and reprogramming, preserving unchanged data elsewhere. The sector address is selected using address lines A7–A16, while A0–A6 specify the byte offset within the 128-byte sector. All 128 bytes must be loaded before internal programming begins, and any unloaded byte reads as FFh after programming.
Can AT29LV010A-15JC be used in industrial temperature applications?
Yes, the AT29LV010A-15JC variant is rated for commercial temperature range (0°C to 70°C) only. For industrial operation (-40°C to +85°C), the correct part is AT29LV010A-15JI (PLCC) or AT29LV010A-15TI (TSOP). The "-J" suffix indicates PLCC packaging, while "-I" or "-T" suffixes denote industrial or commercial temperature grades respectively - mixing these suffixes invalidates temperature compliance. Always verify the full ordering code's temperature rating before deployment.
What package type is used for AT29LV010A-15JC?
AT29LV010A-15JC uses a 32-lead Plastic Leaded Chip Carrier (PLCC) package, designated as "32J" in Atmel's ordering nomenclature. It conforms to JEDEC standard MS-016, Variation AE, with a body size of approximately 12.45 mm × 14.95 mm and 1.27 mm lead pitch. Pin 1 is identified by a corner notch on the top surface, and two pins (13 and 31) are designated NC (no connect) and must remain unconnected in PCB layout.
