Product details
Overview
AT27BV010-90JI 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 supply operation (2.7–3.6 V or 4.5–5.5 V), and industrial temperature range (−40°C to +85°C). It uses CMOS/TTL-compatible I/O, supports Rapid™ programming at 100 µs/byte, and is packaged in 32-lead PLCC.
For engineers reviewing the AT27BV010-90JI datasheet, AT27BV010-90JI pinout, AT27BV010-90JI application, or AT27BV010-90JI equivalent, key selection considerations include unregulated battery voltage support, JEDEC-compatibility with AT27C010, standby current <20 µA at 3.6 V, TSOP/VSOP/PLCC package options, and industrial-grade reliability with 200 mA latchup immunity.
Technical Context
The AT27BV010-90JI implements a standard OTP EPROM architecture with two-line control (CE/OE), enabling bus contention avoidance in shared-memory systems. Its dual-voltage design allows seamless operation across 2.7–3.6 V (LVBO-compliant) and 4.5–5.5 V (LVTTL-compliant) rails without level-shifting circuitry.
Programming relies on external VPP = 13.0 V and VCC = 6.5 V, with integrated Product Identification Code (0x1E/0x05) for automated programmer recognition. The Rapid™ algorithm performs verify-reprogram loops per byte, limiting maximum pulses to 10 before failure declaration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-90JC | 5 V-only operation (4.5–5.5 V); no low-voltage mode; same 90 ns access and PLCC package. | Limited to regulated 5 V systems; cannot operate from unregulated battery sources. | Select when legacy 5 V design requires zero-layout change and low-voltage operation is unnecessary. |
| MX29LV160CBTI-90G | 16 Mbit Flash (2M × 8), 3.0 V core, 90 ns access, but supports erase/write; different command set and pinout. | Enables field-upgradable firmware; requires controller-level software changes and PCB layout revision. | Select only if firmware update capability is required and redesign resources are available. |
Compared with AT27C010-90JC, the AT27BV010-90JI adds unregulated battery support and lower standby power but retains identical timing and footprint; compared with MX29LV160CBTI-90G, it offers simpler interface and guaranteed data retention without wear leveling, at the cost of programmability.

FAQ
What is the operating voltage range for AT27BV010-90JI?
The AT27BV010-90JI operates across two distinct supply ranges: 2.7 V to 3.6 V for low-voltage battery applications and 4.5 V to 5.5 V for standard 5 V systems. It does not support intermediate voltages outside these bands. Both ranges deliver identical 90 ns read access time and full functionality, including TTL-compatible outputs at 3.0 V and LVBO compliance at 2.7 V. This dual-range capability is intrinsic to the AT27BV010-90JI silicon design and requires no external configuration.
Is AT27BV010-90JI pin-compatible with AT27C010?
Yes, the AT27BV010-90JI is JEDEC-standard pin-compatible with the AT27C010 in all supported packages (PLCC, TSOP, VSOP), sharing identical pin functions, numbering, and electrical interface definitions. This allows direct PCB-level substitution in existing AT27C010 designs. However, AT27BV010-90JI introduces additional low-voltage operation and reduced standby current, which do not affect pinout or signal timing behavior-making it a true drop-in upgrade for 5 V systems seeking extended battery life or simplified power architecture.
What programming voltage is required for AT27BV010-90JI?
The AT27BV010-90JI requires VPP = 13.0 V ± 0.25 V and VCC = 6.5 V ± 0.25 V during programming, per the datasheet's DC Programming Characteristics table. These voltages must be applied simultaneously or with VCC leading VPP, and removed simultaneously or with VCC trailing VPP. A 0.1 µF capacitor is mandatory between VPP and GND to suppress transients. The AT27BV010-90JI does not support in-system programming at standard I/O voltages-it strictly requires dedicated EPROM programmers capable of generating these elevated programming supplies.
Does AT27BV010-90JI support read-modify-write operations?
No, the AT27BV010-90JI is a one-time programmable (OTP) EPROM and does not support read-modify-write operations. Once programmed, its contents are permanently fixed and cannot be erased or rewritten. Data integrity is ensured through high-reliability CMOS fabrication with 2,000 V ESD protection and 200 mA latchup immunity, but any modification requires physical device replacement. This makes the AT27BV010-90JI suitable for immutable firmware or calibration data-not for applications requiring field updates or dynamic configuration storage.
What is the meaning of the 'I' suffix in AT27BV010-90JI?
The 'I' in AT27BV010-90JI denotes industrial temperature grade, specifying guaranteed operation from −40°C to +85°C ambient case temperature. This contrasts with the 'C' suffix (commercial grade: 0°C to +70°C). The 'J' indicates 32-lead PLCC packaging per JEDEC MS-016 AE, and '90' specifies 90 ns maximum read access time. All electrical parameters-including standby current, access time, and programming characteristics-are validated across the full −40°C to +85°C range for the AT27BV010-90JI, making it suitable for harsh-environment deployments where thermal stability is critical.
