Product details
Overview
AT27LV010A-70JI from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM with 70 ns read access time, dual-voltage operation (3.0–3.6 V or 4.5–5.5 V), and industrial temperature range (−40°C to +85°C). It features CMOS/TTL-compatible I/O, 20 µA max standby current at 3.6 V, and JEDEC-standard 32-lead PLCC packaging - ideal for battery-powered portable systems requiring low-power nonvolatile storage.
For engineers reviewing the AT27LV010A-70JI datasheet, AT27LV010A-70JI pinout, AT27LV010A-70JI application, or AT27LV010A-70JI equivalent, key selection criteria include its single-supply 3.3 V read capability, rapid 100 µs/byte programming algorithm, TTL-level output compatibility with 5 V systems, and industrial-grade reliability with 2,000 V ESD protection and 200 mA latchup immunity.
Technical Context
The AT27LV010A-70JI implements a two-line control architecture using CE and OE for bus contention management, supporting both read and Rapid™ programming modes. Its internal logic ensures TTL-compatible outputs even when powered at 3.0 V, enabling interoperability with legacy 5 V systems without level-shifting.
Programming requires VCC = 6.5 V and VPP = 13.0 V with a 100 µs ±5% PGM pulse width; verification occurs per-byte with up to 10 reprogramming attempts. The device integrates an electronic Product Identification Code (Manufacturer ID: 0x1E, Device ID: 0x05) accessible via A9 = 12.0 V and A0 toggling - used by standard programmers for auto-algorithm selection.

|---|---|---|---|
| AT27C010-70PC | 5 V only (4.5–5.5 V), no 3.3 V operation; identical 70 ns tACC and PLCC-32 package | Requires dedicated 5 V rail; not suitable for battery-powered or dual-voltage systems | Select when legacy 5 V infrastructure exists and low-voltage operation is unnecessary |
| MX27C1000-70PC | 5 V only, 70 ns access, same 128K × 8 organization but Macronix branding; slightly higher ISB (100 µA) | Lacks integrated product ID code and Rapid™ programming - requires manual programmer setup and longer programming cycles | Choose for cost-sensitive 5 V-only applications where programming speed and auto-ID are not critical |
Compared with AT27C010-70PC and MX27C1000-70PC, the AT27LV010A-70JI uniquely supports 3.3 V operation with TTL-compatible outputs, delivers lower standby current, and includes programmable identification - making it the only option for portable, dual-voltage, or automated-programming use cases.

FAQ
What voltage ranges does the AT27LV010A-70JI support during normal read operation?
The AT27LV010A-70JI supports two distinct read voltage ranges: 3.0 V to 3.6 V (low-voltage mode) and 4.5 V to 5.5 V (standard 5 V mode). Both ranges guarantee 70 ns access time and TTL-compatible output levels. During programming, however, VCC must be raised to 6.5 V and VPP to 13.0 V - these voltages are strictly for programming and must not be applied during read operations. The AT27LV010A-70JI's dual-range capability enables seamless integration into systems that operate across 3 V and 5 V domains.
Is the AT27LV010A-70JI pin-compatible with the AT27C010 series?
Yes, the AT27LV010A-70JI is pin-compatible with the AT27C010 series in JEDEC-standard 32-lead PLCC, TSOP, and VSOP packages. Its pinout matches exactly - including A0–A16, O0–O7, CE, OE, PGM, VCC, VPP, GND, and NC assignments. This allows direct socket replacement in existing AT27C010-based designs. However, note that AT27LV010A-70JI requires different programming voltages (VCC = 6.5 V, VPP = 13.0 V) and supports 3.3 V read operation - both enhancements over the original AT27C010.
What is the purpose of the Integrated Product Identification Code in the AT27LV010A-70JI?
The AT27LV010A-70JI includes an electronically readable Product Identification Code consisting of Manufacturer ID (0x1E) and Device ID (0x05), accessed by applying 12.0 V to A9 and toggling A0. This feature enables industry-standard programmers to auto-detect the device type and select correct programming algorithms and voltage profiles - eliminating manual part selection errors and reducing programming setup time. The AT27LV010A-70JI shares this ID code with the AT27C010, ensuring backward compatibility with existing programming infrastructure.
How does the Rapid™ Programming Algorithm improve efficiency for the AT27LV010A-70JI?
The Rapid™ Programming Algorithm reduces AT27LV010A-70JI programming time to 100 µs per byte (typical), significantly faster than conventional EPROM algorithms. It uses a verify-reprogram loop per byte, applying up to 10 pulses if verification fails. This deterministic approach ensures high first-pass yield and eliminates need for external verification hardware. Because the AT27LV010A-70JI implements this algorithm internally, programmers require only basic timing control - simplifying production line integration and reducing test overhead compared to non-Rapid™ alternatives.
What are the key reliability specifications of the AT27LV010A-70JI?
The AT27LV010A-70JI features 2,000 V human-body-model (HBM) ESD protection and 200 mA latchup immunity - validated per JEDEC standards. Its industrial temperature range (−40°C to +85°C) and 100-year data retention (at 125°C accelerated testing) confirm suitability for demanding environments. The device also includes design safeguards such as strict sequencing requirements (VCC applied before VPP) and mandatory decoupling (0.1 µF ceramic + 4.7 µF bulk capacitor), which the AT27LV010A-70JI datasheet specifies to prevent transient-induced non-conformance.
