Product details
Overview
AT27BV010-90JU from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM optimized for low-voltage, battery-powered systems. It operates across dual supply ranges (2.7V–3.6V unregulated or 4.5V–5.5V standard), delivers 90ns read access time at VCC = 2.7V, draws ≤20µA standby current, and supports JEDEC-standard PLCC-32 packaging with CMOS/TTL-compatible I/O.
For engineers reviewing the AT27BV010-90JU datasheet, AT27BV010-90JU pinout, AT27BV010-90JU application, or AT27BV010-90JU equivalent, key selection criteria include its dual-voltage read capability, rapid 100µs/byte programming algorithm, industrial temperature range (−40°C to +85°C), and compatibility with AT27C010 programming infrastructure.
Technical Context
The AT27BV010-90JU implements a single-supply OTP EPROM architecture with two-line control (CE/OE) enabling bus contention avoidance in embedded memory subsystems. Its internal design integrates product identification code logic (manufacturer ID 0x1E, device ID 0x05) and supports both LVBO (2.7V–3.6V) and LVTTL (4.5V–5.5V) interface standards without level-shifting circuitry.
Programming requires VCC = 6.5V and VPP = 13.0V with a 100µs ±5% PGM pulse width; verification occurs per-byte with up to 10 reprogramming attempts before failure declaration. The device uses high-reliability CMOS technology featuring 2,000V HBM ESD protection and 200mA latchup immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 1,048,576-bit (128K × 8) OTP EPROM - fixed storage for firmware/boot code in space-constrained systems |
| Read access time | 90ns max at VCC = 2.7V - enables real-time data retrieval in portable instrumentation and legacy controller upgrades |
| Supply voltage range | 2.7V–3.6V (unregulated battery) or 4.5V–5.5V (standard) - eliminates need for external regulators in mixed-voltage host environments |
| Standby current | 20µA max (CMOS mode), <1µA typical at 3V - extends battery life in always-on monitoring devices |
| Active power @5MHz | 29mW max at VCC = 3.6V - consumes <20% of equivalent 5V EPROMs, reducing thermal load in dense PCB layouts |

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 | 5V-only operation (4.5V–5.5V); no 2.7V–3.6V support; identical 90ns access, PLCC-32, and programming algorithm | Limited to fixed 5V systems; cannot replace AT27BV010-90JU in battery-powered or dual-voltage hosts | Select when legacy 5V infrastructure prohibits voltage scaling and green (Pb/halide-free) packaging is not required |
| MX27C1001PC-12 | 120ns access time; 5V-only; 32-pin PDIP package; no integrated ID code; higher 50mA active current | Suitable only for cost-sensitive, non-portable applications where speed and power are secondary to procurement availability | Choose only if PLCC-to-PDIP adapter is acceptable and 30ns slower access does not violate system timing budgets |
Compared with AT27C010-90JU and MX27C1001PC-12, the AT27BV010-90JU uniquely supports unregulated battery operation while maintaining 90ns performance and industrial temperature tolerance-making it the sole option for portable, mixed-voltage, or thermally demanding deployments.

FAQ
What is the maximum operating voltage for VPP on the AT27BV010-90JU during programming?
The AT27BV010-90JU requires VPP = 13.0V ±0.25V during programming operations, with absolute maximum rating of +14.0V. Exceeding this voltage risks permanent damage to the oxide layer. The AT27BV010-90JU datasheet specifies that VPP must be applied simultaneously with or after VCC, and removed simultaneously with or after VCC, to prevent latchup or overvoltage stress on internal circuitry.
Can the AT27BV010-90JU operate reliably at 2.7V while maintaining its 90ns access time specification?
Yes, the AT27BV010-90JU guarantees tACC ≤90ns at VCC = 2.7V across the full industrial temperature range (−40°C to +85°C). This is explicitly confirmed in Table 5-4 of the official datasheet. The AT27BV010-90JU achieves this through optimized low-voltage core design, enabling true unregulated battery operation without performance degradation.
Is the AT27BV010-90JU pin-compatible with the AT27C010-90JU?
Yes, the AT27BV010-90JU is fully pin-compatible with the AT27C010-90JU in the PLCC-32 package, sharing identical pinout, address/data bus mapping, and control signal definitions (CE, OE, PGM). The AT27BV010-90JU maintains JEDEC-standard compatibility and uses the same programming equipment, though it adds 2.7V–3.6V operation and green packaging.
What decoupling capacitance is required for stable operation of the AT27BV010-90JU?
The AT27BV010-90JU requires a minimum 0.1µF high-frequency ceramic capacitor placed between VCC and GND, located as close as possible to the device pins. For systems with multiple EPROMs, a 4.7µF bulk electrolytic capacitor should also be added near the power entry point. These values are specified in Section 3 ("System considerations") of the AT27BV010-90JU datasheet to suppress transient excursions during CE transitions.
Does the AT27BV010-90JU support in-system programming?
No, the AT27BV010-90JU is a one-time programmable (OTP) EPROM designed for programming in dedicated EPROM programmers prior to system integration. It lacks serial interfaces, command protocols, or erase functionality required for in-system programming. The AT27BV010-90JU programming sequence mandates external VPP = 13.0V and precise 100µs PGM pulses - features incompatible with standard microcontroller GPIO-based programming.
