Product details
Overview
AT27LV010A-12JI from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM optimized for low-voltage battery-powered systems, featuring 70 ns read access time at 3.0–3.6 V, dual 3.3 V / 5 V supply compatibility, and industrial temperature range (−40°C to +85°C). It uses JEDEC-standard PLCC-32 packaging and supports rapid programming at 100 µs/byte.
For engineers reviewing the AT27LV010A-12JI datasheet, AT27LV010A-12JI pinout, AT27LV010A-12JI application, or AT27LV010A-12JI equivalent, key selection criteria include standby current (<20 µA at VCC = 3.6 V), TTL/CMOS I/O compatibility, JEDEC AT27C010 functional equivalence, and industrial-grade reliability with 2,000 V ESD protection.
Technical Context
The AT27LV010A-12JI implements a standard OTP EPROM architecture with two-line control (CE/OE), enabling bus contention avoidance in multi-device systems. Its dual-voltage operation allows seamless integration into mixed-supply environments-TTL-level outputs at 3.0 V are compatible with 5 V logic, while full 5 V ±10% operation remains supported.
Programming relies on external VPP = 13.0 V and VCC = 6.5 V, with Rapid™ algorithm executing 100 µs pulses and up to 10 retries per byte. Product identification uses dedicated A9/VH and A0 toggling to select manufacturer (0x1E) and device code (0x05) bytes-identical to AT27C010 for programming equipment compatibility.

Use Scenario: Replacing obsolete 5 V EPROMs in aging test equipment and process controllers where board redesign is cost-prohibitive. IC Role / Device Role / Timing Role: Drop-in JEDEC AT27C010-compatible memory enabling field upgrades without PCB changes or firmware adaptation. Use Value: Pinout, timing, and programming equivalence to AT27C010 permits direct socket replacement - eliminating NRE costs and validation delays. |
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 | 5 V only (4.5–5.5 V); no 3.3 V operation; same 120 ns tACC, PLCC-32 package | Restricted to legacy 5 V systems; lacks low-power advantage for battery operation | Select when existing 5 V infrastructure prohibits voltage scaling and industrial temp not required |
| MN63C1000P-12 | Same 128K × 8 OTP EPROM; 120 ns access; 5 V only; PLCC-32; manufactured by Macronix | Requires separate programming voltage setup; no integrated product ID code | Choose for second-source assurance in long-lifecycle 5 V-only designs where Atmel supply continuity is constrained |
Compared with AT27C010-12JC, the AT27LV010A-12JI adds 3.3 V operation and lower standby current but shares identical pinout and programming flow; versus MN63C1000P-12, it offers built-in ID code and tighter ESD/latchup specs, simplifying programmer integration and field reliability.

FAQ
What voltage levels does the AT27LV010A-12JI support during normal read operation?
The AT27LV010A-12JI supports two distinct read supply ranges: 3.0 V to 3.6 V for low-power portable applications and 4.5 V to 5.5 V for compatibility with legacy 5 V systems. Both ranges deliver guaranteed 120 ns access time, and outputs meet TTL voltage thresholds even at 3.0 V, enabling direct interfacing with 5 V logic without level shifters.
Is the AT27LV010A-12JI pin-compatible with the AT27C010 series?
Yes, the AT27LV010A-12JI is fully pin-compatible with the AT27C010 family, including identical PLCC-32 pinout, signal naming, and DC/AC timing specifications. This allows direct socket replacement in existing designs, preserving PCB layout and firmware toolchains while adding 3.3 V operation and reduced power consumption.
What programming voltage and equipment are required for the AT27LV010A-12JI?
The AT27LV010A-12JI requires VPP = 13.0 V ± 0.25 V and VCC = 6.5 V ± 0.25 V during programming, with a 100 µs PGM pulse width. It uses the same programming algorithms and hardware as the AT27C010, including industry-standard programmers that recognize its integrated product ID (0x1E/0x05) for automatic setup.
Does the AT27LV010A-12JI support industrial temperature operation?
Yes, the AT27LV010A-12JI is rated for industrial temperature operation from −40°C to +85°C, as confirmed by its "I" suffix in the ordering code. This qualification includes full functionality across the entire range for read access time, standby current, and I/O voltage thresholds - validated per JEDEC JESD22-A108.
How does the Rapid™ Programming Algorithm improve production efficiency for the AT27LV010A-12JI?
The Rapid™ Programming Algorithm reduces average programming time to 100 µs per byte - approximately five times faster than conventional EPROM algorithms. For the full 128K-byte array, this cuts total programming duration to under 13 seconds, significantly accelerating firmware burn-in and reducing test floor throughput bottlenecks in high-volume manufacturing.
