Product details
Overview
AT27BV010-12JI from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM optimized for low-voltage battery-powered systems, featuring 90 ns read access time, dual-voltage operation (2.7–3.6V or 4.5–5.5V), and industrial temperature range (−40°C to +85°C). It delivers TTL/CMOS-compatible outputs, rapid 100 µs/byte programming, and JEDEC-standard PLCC-32 packaging.
For engineers reviewing the AT27BV010-12JI datasheet, AT27BV010-12JI pinout, AT27BV010-12JI application, or AT27BV010-12JI equivalent, key selection criteria include unregulated battery voltage support, standby current under 20 µA at 3.6V, compatibility with AT27C010 programming infrastructure, and industrial-grade reliability with 2,000V ESD protection.
Technical Context
The AT27BV010-12JI implements a standard OTP EPROM architecture with two-line control (CE/OE), enabling bus contention avoidance in shared-memory systems. Its dual-supply design supports both unregulated 2.7–3.6V battery rails and legacy 5V ±10% systems without level-shifting.
It uses Atmel's Rapid™ Programming Algorithm requiring VCC = 6.5V and VPP = 13.0V during programming, with integrated product identification (Manufacturer ID: 0x1E, Device ID: 0x05) for automated programmer recognition. Output drive strength meets LVTTL/LVBO standards across its full operating voltage range.

Applications
| Industrial PLC Firmware Storage | Medical Diagnostic Boot ROM |
|---|---|
|
Use Scenario: Fixed firmware storage in programmable logic controllers deployed in factory automation environments with wide ambient temperature swings. IC Role / Device Role / Timing Role: Non-volatile boot code repository accessed during cold start; provides deterministic 120 ns read latency for real-time initialization. Use Value: Industrial temperature rating (−40°C to +85°C) and 2,000V ESD tolerance ensure reliable operation in electrically noisy plant-floor settings. |
Use Scenario: Secure, tamper-resistant storage of calibration and diagnostic routines in portable ultrasound and ECG devices powered by lithium batteries. IC Role / Device Role / Timing Role: OTP memory holding immutable startup sequences; operates directly from unregulated 3.0V battery rail without DC-DC conversion. Use Value: 20 µA max standby current extends battery runtime between charges; LVBO interface eliminates level-shifters in compact PCB layouts. |
| Automotive Body Control Module | Legacy Industrial Instrumentation |
|
Use Scenario: Storing configuration tables and safety-critical initialization code in vehicle door modules and lighting controllers. IC Role / Device Role / Timing Role: Read-only memory mapped into microcontroller address space; accessed via 8-bit parallel bus with CE/OE handshaking. Use Value: Dual-voltage support allows reuse across 12V (5V-regulated) and 24V (3.3V-regulated) vehicle platforms using identical firmware images. |
Use Scenario: Replacement for obsolete AT27C010 in aging test equipment and process controllers requiring long-term component availability.

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 2.7–3.6V support; identical 120 ns tACC and PLCC-32 pinout. | Restricted to regulated 5V systems; lacks battery-voltage flexibility. | Select when upgrading legacy 5V-only designs where VCC regulation is already present and low-power standby is non-critical. |
| MN65E1000BGP | Same 128K × 8 OTP EPROM; 150 ns tACC; 3.3V-only operation (2.7–3.6V); TSOP-32 only - no PLCC option. | Requires PCB redesign due to different package; slower access time limits high-speed bus use. | Choose only if TSOP-32 footprint is mandated and 150 ns latency is acceptable; verify programming voltage compatibility (VPP = 12.5V). |
Compared with AT27C010-12JC, the AT27BV010-12JI adds unregulated battery operation and cuts standby current by 80%, while MN65E1000BGP trades speed and package compatibility for TSOP miniaturization - making AT27BV010-12JI optimal for industrial battery-powered upgrades requiring zero layout change.

FAQ
What voltage ranges does the AT27BV010-12JI support during normal read operation?
The AT27BV010-12JI supports two distinct read voltage ranges: 2.7V to 3.6V for unregulated battery operation and 4.5V to 5.5V for standard 5V systems. It does not operate at intermediate voltages like 4.0V. Both ranges deliver full functionality including 120 ns access time and TTL-compatible outputs, with no external level shifting required.
Is the AT27BV010-12JI pin-compatible with the AT27C010 series?
Yes, the AT27BV010-12JI is pin-compatible with the AT27C010 in PLCC-32 packaging, sharing identical pin functions, address/data mapping, and CE/OE control logic. However, AT27BV010-12JI requires separate VPP routing (13.0V) and updated power sequencing - VCC must be applied before and removed after VPP - unlike the AT27C010's single 5V supply.
What programming equipment is required for the AT27BV010-12JI?
The AT27BV010-12JI uses the same programming algorithms and hardware as the AT27C010, including industry-standard EPROM programmers with VPP = 13.0V capability. Its integrated product ID (0x1E/0x05) ensures automatic recognition. A 0.1 µF capacitor must be placed between VPP and GND on the programmer interface to suppress transients during programming pulses.
Does the AT27BV010-12JI support read operations at 2.7V with full timing specifications?
Yes, the AT27BV010-12JI guarantees 120 ns maximum access time (tACC) and full DC/AC parametric compliance down to 2.7V VCC. Output drive strength remains sufficient for TTL loads at this minimum voltage, and input thresholds scale with VCC (e.g., VIH = 0.7 × VCC), ensuring robust noise margins in battery-depleted conditions.
What is the purpose of the PGM pin on the AT27BV010-12JI?
The PGM pin on the AT27BV010-12JI is an active-low strobe that initiates byte programming when pulsed for 95–105 µs with VCC = 6.5V and VPP = 13.0V applied. It triggers the Rapid™ algorithm's verify-and-reprogram loop. During read or standby modes, PGM must be held high (VIH) to prevent unintended programming - no pull-up is internal, so external biasing is required.
