Product details
Overview
AT27BV010-90JC 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 JEDEC-standard 32-lead PLCC packaging. It delivers TTL-compatible outputs at 3.0 V and supports rapid programming at 100 µs/byte - ideal for portable instrumentation and embedded firmware storage.
For engineers reviewing the AT27BV010-90JC datasheet, AT27BV010-90JC pinout, AT27BV010-90JC application, or AT27BV010-90JC equivalent, key selection criteria include unregulated battery voltage support (2.7–3.6 V), 90 ns read timing, industrial temperature range (−40°C to +85°C), PLCC package compatibility, and OTP programming reliability with integrated product identification code.
Technical Context
The AT27BV010-90JC implements a CMOS-based OTP memory architecture with two-line control (CE/OE), enabling bus contention avoidance in shared-data-bus systems. Its dual-voltage design allows seamless operation across regulated 5 V and unregulated 2.7–3.6 V battery rails without level-shifting circuitry.
It uses Atmel's Rapid™ Programming Algorithm with 100 µs/byte typical pulse width and on-chip product identification (Manufacturer ID = 0x1E, Device ID = 0x05), ensuring compatibility with standard AT27C010 programmers. Programming requires VCC = 6.5 V and VPP = 13.0 V, while read mode operates at VCC only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,048,576-bit (128K × 8) OTP EPROM - fixed firmware storage with no erase capability. |

IC Role / Device Role / Timing Role: Immutable configuration and safety-critical boot code storage; accessed exclusively during MCU reset vector fetch. Use Value: 200 mA latchup immunity and −40°C to +85°C operation meet AEC-Q100 stress requirements; low standby current preserves parasitic drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

| AT27C010-90PC | 5 V-only supply (4.5–5.5 V); no 2.7–3.6 V operation; same 90 ns speed and PLCC package. | Requires regulated 5 V rail; unsuitable for direct battery connection or mixed-voltage systems. | Select when legacy 5 V infrastructure exists and battery operation is not needed. |
| MX27C1000-12PC | 120 ns access time; 5 V-only; higher standby current (100 µA); same 128K × 8 OTP structure. | Slower boot timing; higher active power; lacks rapid programming and product ID features. | Select when cost sensitivity outweighs speed/power advantages and AT27BV010-90JC availability is constrained. |
Compared with AT27C010-90PC and MX27C1000-12PC, the AT27BV010-90JC uniquely supports unregulated battery voltage operation, achieves lower standby current, and integrates rapid programming and electronic ID - making it the optimal choice for next-generation portable and automotive firmware storage where power efficiency and programming flexibility are critical.

FAQ
What voltage ranges does the AT27BV010-90JC support during normal read operation?
The AT27BV010-90JC supports two distinct read-mode voltage ranges: 2.7 V to 3.6 V for unregulated battery applications and 4.5 V to 5.5 V for standard 5 V logic systems. It does not operate at intermediate voltages like 4.0 V. Both ranges deliver guaranteed 90 ns access time, and the device automatically adapts output drive strength and logic thresholds to match the applied VCC - eliminating external level shifters in dual-rail designs.
Is the AT27BV010-90JC pin-compatible with the AT27C010?
Yes, the AT27BV010-90JC is fully pin-compatible and functionally equivalent to the AT27C010 in read and programming modes, including identical pinout, timing parameters, and programming voltage sequencing. The AT27BV010-90JC retains the same JEDEC-standard 32-lead PLCC footprint and signal assignments, allowing direct PCB replacement in legacy designs - provided the system can accommodate its dual-voltage capability and lower power profile.
What programming voltage and sequence are required for the AT27BV010-90JC?
The AT27BV010-90JC requires VCC = 6.5 V ± 0.25 V and VPP = 13.0 V ± 0.25 V for programming, with strict sequencing: VCC must be applied simultaneously with or before VPP, and removed simultaneously with or after VPP. A 0.1 µF capacitor is mandatory between VPP and GND to suppress transients. Programming uses 100 µs PGM pulses and leverages the integrated product ID code to auto-configure programmer algorithms - identical to AT27C010 workflows.
Does the AT27BV010-90JC support industrial temperature operation?
Yes, the AT27BV010-90JC is qualified for industrial temperature operation from −40°C to +85°C, as confirmed by the "I" suffix in ordering codes (e.g., AT27BV010-90JI). This rating applies to both read and standby modes under specified voltage ranges and is verified per JEDEC JESD22-A104 and JESD22-A108 standards - making it suitable for under-hood automotive modules and factory-floor controllers.
How does the Rapid™ Programming Algorithm improve production throughput for the AT27BV010-90JC?
The Rapid™ Programming Algorithm reduces average programming time to ~100 µs per byte with built-in verification and up to 10 reprogramming attempts per failed byte - cutting total 128K-byte programming time by more than 5× versus conventional EPROM algorithms. This enables faster firmware burn-in during manufacturing, reduces programmer dwell time, and improves yield consistency without requiring special equipment - all while maintaining full compatibility with standard AT27C010 programming hardware.
