Product details
Overview
AT27LV010A-12TC from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM optimized for low-voltage battery-powered systems, featuring 120 ns read access time, dual 3.0–3.6V or 4.5–5.5V supply operation, and JEDEC-standard 32-lead TSOP packaging. It serves as nonvolatile program storage in embedded controllers and legacy BIOS modules.
For engineers reviewing the AT27LV010A-12TC datasheet, AT27LV010A-12TC pinout, AT27LV010A-12TC application, or AT27LV010A-12TC equivalent, key selection criteria include standby current (<20 µA at VCC = 3.6V), TTL/CMOS I/O compatibility, Rapid™ programming (100 µs/byte), JEDEC AT27C010 compatibility, and industrial temperature support (–40°C to +85°C).
Technical Context
The AT27LV010A-12TC implements a standard OTP EPROM architecture with two-line control (CE/OE), supporting fast random-access reads and rapid byte-level programming via dedicated PGM strobe. Its dual-voltage design enables interoperability with both 3.3V and 5V logic families without level-shifting.
It features integrated product identification (manufacturer code 0x1E, device code 0x05), 2,000V ESD protection, and latchup immunity of 200 mA. Programming requires VCC = 6.5V and VPP = 13.0V, with strict sequencing (VCC applied before/with VPP) and on-board decoupling (0.1 µF ceramic + 4.7 µF bulk capacitor).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,048,576-bit (128K × 8) OTP EPROM - fixed, non-erasable storage for firmware or boot code. |
| Read Access Time | 120 ns max at VCC = 3.0–3.6V or 4.5–5.5V - meets timing for 8 MHz bus interfaces in legacy microcontrollers. |
| Supply Voltage Range | 3.0–3.6V or 4.5–5.5V - supports dual-supply systems and hot-plug compatibility across 3V/5V hosts. |
| Standby Current | 20 µA max at VCC = 3.6V - enables multi-year battery life in portable instrumentation and remote sensors. |
| Active Power Dissipation | 29 mW max at 5 MHz, VCC = 3.6V - reduces thermal load in dense PCB layouts with multiple EPROMs. |
| Programming Speed | 100 µs/byte typical (Rapid™ algorithm) - cuts firmware update time by >5× vs. conventional EPROMs. |
| I/O Compatibility | JEDEC LVTTL-compliant inputs/outputs - directly interfaces with 74LVC, 74ALVC, and standard 5V TTL logic. |
Pinout & Package

| OE | Output Enable | Active-low output gate; allows shared bus operation without contention when CE is asserted. |
| PGM | Program Strobe | Active-low pulse input triggering byte programming; requires precise 95–105 µs width at VPP = 13.0V. |
| VCC | Power Supply | Main supply pin; must be applied simultaneously with or before VPP during programming to prevent damage. |
| VPP | Programming Voltage | 13.0V ± 0.25V programming supply; requires external decoupling and strict sequencing with VCC. |
| GND | Ground Reference | Signal and power return; requires local 0.1 µF ceramic capacitor placement per device per datasheet. |
| NC | No Connect | Pin 6 (TSOP top view); electrically isolated - must remain unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-12JC | 5V-only operation (4.5–5.5V); no low-voltage mode; same 120 ns tACC and 32-lead PLCC package. | Requires dedicated 5V rail; unsuitable for battery-powered or mixed-voltage systems. | Select when board already uses 5V logic and no low-power standby is required. |
| MX27C1000-12PC | 5V-only, 120 ns access, 32-pin PDIP package; lacks Rapid™ programming and product ID code. | Through-hole mounting only; no TSOP option; slower programming and no automated programmer ID support. | Choose for prototyping or legacy through-hole designs where surface-mount density is not critical. |
Compared with AT27LV010A-12TC, AT27C010-12JC offers identical speed and pinout but sacrifices low-voltage flexibility and battery efficiency, while MX27C1000-12PC trades modern packaging and programming features for mechanical compatibility with hand-soldered breadboard environments.

FAQ
What is the maximum read access time specified for AT27LV010A-12TC?
The AT27LV010A-12TC has a maximum read access time of 120 ns under all valid operating conditions (VCC = 3.0–3.6V or 4.5–5.5V, TA = –40°C to +85°C). This value is guaranteed across commercial and industrial temperature ranges and applies to both CE- and OE-controlled read cycles as defined in the AC characteristics table.
Does AT27LV010A-12TC support true 3.3V-only operation without 5V logic compatibility?
Yes, AT27LV010A-12TC operates fully within 3.0–3.6V for read mode and delivers TTL-compatible outputs (VOH ≥ 2.4V, VOL ≤ 0.4V) that interface directly with standard 5V TTL logic, even when VCC = 3.3V. This dual compatibility eliminates external level shifters in mixed-voltage systems.
Can AT27LV010A-12TC be programmed using standard AT27C010 programming equipment?
Yes, AT27LV010A-12TC programs identically to AT27C010 using the same equipment, algorithms, and pinout. Its integrated product ID code (0x1E/0x05) ensures automatic recognition by industry-standard programmers, and it accepts the same 100 µs PGM pulses with VCC = 6.5V and VPP = 13.0V.
What decoupling capacitors are required for stable operation of AT27LV010A-12TC?
Per the datasheet, each AT27LV010A-12TC requires a 0.1 µF high-frequency ceramic capacitor placed between VCC and GND as close to the device as possible. For arrays, a 4.7 µF bulk electrolytic capacitor must also be added near the power entry point to stabilize the supply rail during simultaneous access events.
Is AT27LV010A-12TC available in packages other than TSOP?
Yes, AT27LV010A-12TC specifically denotes the 32-lead TSOP (32T) variant, but the same speed grade is offered in 32-lead PLCC (AT27LV010A-12JC) and 32-lead VSOP (AT27LV010A-12VC). All share identical electrical specifications, timing, and programming behavior - only mechanical form factor differs.
