Product details
Overview
AT27BV010-15JI from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM optimized for low-voltage battery-powered systems, featuring 150 ns read access time, dual-voltage operation (2.7–3.6 V or 4.5–5.5 V), and industrial temperature range (−40°C to +85°C). It delivers TTL- and LVTTL-compatible outputs, 20 µA max standby current at 3.6 V, and JEDEC-standard 32-lead PLCC packaging - ideal for portable instrumentation and embedded firmware storage.
For engineers reviewing the AT27BV010-15JI datasheet, AT27BV010-15JI pinout, AT27BV010-15JI application, or AT27BV010-15JI equivalent, key selection criteria include unregulated battery voltage support, rapid 100 µs/byte programming, integrated product identification code, JEDEC-compatibility with AT27C010, and industrial-grade reliability with 2,000 V ESD protection.
Technical Context
The AT27BV010-15JI implements a CMOS OTP EPROM architecture with two-line control (CE/OE), enabling bus contention avoidance in multi-device systems. Its dual-supply design supports both unregulated 2.7–3.6 V battery rails and standard 5 V ±10% operation without external level shifting.
It uses Atmel's Rapid™ Programming Algorithm requiring VCC = 6.5 V and VPP = 13.0 V during programming, with built-in product identification via A9/VH and A0 toggling. The device maintains full compatibility with AT27C010 programming equipment and algorithms while delivering lower power consumption than 5 V equivalents.

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-15JC | Requires 5 V ±10% only; no 2.7–3.6 V operation; same 150 ns access, PLCC-32 package, and programming method. | Restricted to regulated 5 V systems; unsuitable for battery-powered or mixed-voltage designs. | Select when legacy 5 V infrastructure exists and battery operation is not required. |
| MX27C1001-15PC | 5 V-only supply; 150 ns access; PLCC-32; compatible pinout but different product ID and programming voltage (VPP = 12.5 V). | Lacks unregulated battery support and integrated ID code; requires programmer firmware update for ID recognition. | Choose for cost-sensitive 5 V applications where Atmel-specific features like Rapid™ programming are unnecessary. |
Compared with AT27C010-15JC and MX27C1001-15PC, the AT27BV010-15JI uniquely supports unregulated battery rails down to 2.7 V while retaining full AT27C010 software and hardware compatibility - making it the only option for upgrading legacy 5 V designs to battery operation without PCB revision.

FAQ
What voltage ranges does the AT27BV010-15JI support during normal read operation?
The AT27BV010-15JI supports two distinct supply ranges for read operation: 2.7 V to 3.6 V (unregulated battery mode) and 4.5 V to 5.5 V (standard 5 V ±10% mode). Both ranges deliver guaranteed 150 ns access time. Operation outside these ranges - including intermediate voltages like 4.0 V - is not specified and may result in timing violations or data corruption. The AT27BV010-15JI must not be operated at 6.5 V or 13.0 V except during verified programming sequences.
Is the AT27BV010-15JI pin-compatible with the AT27C010?
Yes, the AT27BV010-15JI is fully pin-compatible with the AT27C010 in all JEDEC-standard packages (PLCC, TSOP, VSOP), including identical pin functions, numbering, and physical footprint. This allows direct substitution in existing AT27C010 layouts. However, the AT27BV010-15JI requires VPP = 13.0 V for programming, whereas the AT27C010 uses VPP = 12.5 V - programming equipment must be configured accordingly to avoid under-programming.
What is the purpose of the PGM pin on the AT27BV010-15JI?
The PGM pin on the AT27BV010-15JI is an active-low strobe that initiates byte programming when asserted with a 95–105 µs pulse width while VCC = 6.5 V and VPP = 13.0 V. It is not used during read or standby modes. The AT27BV010-15JI implements Atmel's Rapid™ Programming Algorithm, where each PGM pulse attempts to program one byte, followed by verification - up to 10 pulses per byte may be applied before failure declaration.
How does the AT27BV010-15JI achieve compatibility with both 3 V and 5 V logic families?
The AT27BV010-15JI achieves dual-voltage interface compatibility through adaptive output drive strength and threshold referencing. At VCC = 3.0 V, its VOH exceeds 2.4 V and VOL remains below 0.4 V - meeting TTL input thresholds. At VCC = 2.7 V, it complies with JEDEC LVBO specifications. Input thresholds (VIL/VIH) scale with VCC, ensuring reliable recognition of 3 V and 5 V logic signals without external level translation circuitry.
What decoupling capacitors are required for stable operation of the AT27BV010-15JI?
The AT27BV010-15JI requires two decoupling capacitors: a 0.1 µF high-frequency ceramic capacitor placed between VCC and GND as close as possible to the device pins to suppress switching transients, and a 4.7 µF bulk electrolytic capacitor located near the power entry point of the PCB to stabilize the supply rail under dynamic load. These values are specified in the "System Considerations" section of the AT27BV010-15JI datasheet and are mandatory for reliable operation across temperature and voltage ranges.
