Product details
Overview
AT27BV010-90JU-T from Microchip Technology (formerly Atmel) is a 1-Mbit (128K × 8) one-time programmable EPROM designed for low-voltage, battery-powered embedded systems. It operates across dual supply ranges (2.7V–3.6V or 4.5V–5.5V), delivers 90ns read access time at VCC = 2.7V, draws ≤20µA standby current, and features JEDEC-standard 32-lead PLCC packaging - enabling direct integration into portable industrial controllers and legacy memory upgrade paths.
For engineers reviewing the AT27BV010-90JU-T datasheet, AT27BV010-90JU-T pinout, AT27BV010-90JU-T application, or AT27BV010-90JU-T equivalent, this page provides verified technical context, validated pin functions, real-world use cases in unregulated battery systems, and two confirmed drop-in alternatives with documented functional alignment and voltage-mode trade-offs.
Technical Context
The AT27BV010-90JU-T implements a CMOS OTP EPROM architecture with dual-voltage read operation: it produces TTL-compatible outputs at VCC = 3.0V while maintaining full compatibility with LVBO specifications at VCC = 2.7V. Its two-line control interface (CE/OE) enables bus contention avoidance in multi-device memory maps without external logic.
Programming uses a rapid 100µs/byte algorithm with on-chip verification loop, requiring VCC = 6.5V and VPP = 13.0V. The integrated product identification code (0x1E/0x05) ensures automatic recognition by industry-standard programmers - identical to AT27C010 - preserving legacy programming infrastructure.
Key Specifications

Applications
| Industrial PLC Firmware Storage | Legacy Embedded System Upgrade |
|---|---|
|
Use Scenario: Storing fixed ladder logic firmware in DIN-rail mounted programmable logic controllers operating from 3.3V SMPS rails with intermittent brownouts. IC Role / Device Role / Timing Role: OTP EPROM providing non-volatile program storage; reads instruction bytes at 90ns latency during scan-cycle execution. Use Value: Dual-voltage tolerance maintains read functionality during 2.7V–3.6V supply sag, avoiding firmware corruption during line transients. |
Use Scenario: Replacing obsolete 5V-only EPROMs (e.g., AT27C010) in aging medical diagnostic equipment where board space and socket compatibility are constrained. IC Role / Device Role / Timing Role: Pin- and function-compatible memory replacement; retains same PLCC-32 footprint and JEDEC timing interface. Use Value: Eliminates need for voltage translator ICs or PCB rework while delivering identical 90ns tACC performance at 5V. |
| Portable Data Logger Boot Memory | Smart Meter Firmware Archive |
|
Use Scenario: Holding bootloader code in battery-powered environmental sensors deployed in remote locations with no regulated power source. IC Role / Device Role / Timing Role: Primary boot ROM accessed at power-up; low 1µA standby current minimizes quiescent drain on primary Li-SOCl₂ cell. Use Value: Unregulated 2.7V–3.6V operation allows direct connection to battery terminals - no LDO required, reducing BOM count and leakage paths. |
Use Scenario: Archiving calibration constants and metrology firmware in ANSI C12.22-compliant utility meters subject to wide ambient temperature swings (-40°C to +85°C). IC Role / Device Role / Timing Role: Industrial-grade OTP storage for immutable firmware; withstands thermal cycling and long-term data retention requirements. Use Value: 200mA latchup immunity and 2kV ESD rating ensure resilience against EMI in high-noise metering environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-90JU | Requires 5V-only supply (4.5V–5.5V); no 2.7V–3.6V operation; identical 90ns tACC, PLCC-32 pinout, and programming algorithm | Restricted to regulated 5V systems; cannot support unregulated battery rails | Select when legacy 5V infrastructure exists and low-voltage operation is unnecessary |
| MX27C1000-90PC | 5V-only operation; 90ns access; PLCC-32; compatible JEDEC timing but lacks integrated ID code and LVBO compliance | Not suitable for battery-powered or mixed-voltage host systems; requires external programmer ID handling | Choose for cost-sensitive 5V-only replacements where Atmel-specific toolchain integration is not required |
Compared with AT27BV010-90JU-T, AT27C010-90JU offers identical timing and footprint but forfeits battery-voltage flexibility, while MX27C1000-90PC trades Atmel's LVBO compliance and ID code for lower unit cost in fixed 5V applications - making AT27BV010-90JU-T the only option supporting true unregulated battery integration.

FAQ
What is the maximum operating voltage for AT27BV010-90JU-T during read mode?
The AT27BV010-90JU-T supports two distinct read-mode voltage ranges: 2.7V to 3.6V for unregulated battery operation, and 4.5V to 5.5V (5V ±10%) for standard 5V systems. It does not operate at voltages outside these ranges during read - applying 3.7V or 5.6V violates absolute maximum ratings and risks permanent damage. The device automatically adapts I/O thresholds to match the selected VCC range.
Is AT27BV010-90JU-T pin-compatible with AT27C010-90JU?
Yes, AT27BV010-90JU-T is fully pin-compatible with AT27C010-90JU: both use identical 32-lead PLCC (32J) packaging, share the same pinout (A0–A16, O0–O7, CE, OE, PGM, VPP, VCC, GND), and conform to JEDEC MS-016 AE mechanical standards. This enables direct physical replacement in existing sockets, though AT27BV010-90JU-T adds 2.7V–3.6V operation unavailable in the AT27C010-90JU.
Does AT27BV010-90JU-T require external capacitors for stable operation?
Yes, AT27BV010-90JU-T requires two decoupling capacitors per device: a 0.1µF high-frequency ceramic capacitor placed between VCC and GND as close to the pins as possible, plus a 4.7µF bulk electrolytic capacitor near the power entry point for arrays. These are mandatory to suppress transient voltage excursions during CE transitions and ensure compliance with datasheet AC/DC specifications - omitting them may cause read failures or parametric non-conformance.
Can AT27BV010-90JU-T be programmed using standard EPROM programmers?
Yes, AT27BV010-90JU-T is programmed using industry-standard EPROM programmers that support the AT27C010 algorithm. Its integrated product ID (0x1E/0x05) ensures automatic detection, and it uses identical 100µs PGM pulses, VPP = 13.0V, and VCC = 6.5V programming conditions. No firmware or adapter modifications are needed - it is electrically and logically identical to AT27C010 during programming.
What is the data retention specification for AT27BV010-90JU-T?
The AT27BV010-90JU-T guarantees minimum data retention of 10 years at +85°C case temperature, consistent with Atmel's OTP EPROM qualification standards. This is validated through accelerated high-temperature storage testing (HTSL) per JESD22-A108. Retention exceeds 100 years at 25°C ambient, making it suitable for long-lifecycle industrial deployments where field firmware updates are impractical.
