Product details
Overview
AT27BV010-15JC 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 JEDEC-standard 32-lead PLCC packaging. It delivers TTL- and LVBO-compatible I/O, <1 µA typical standby current at 3V, and supports rapid programming at 100 µs/byte for portable instrumentation and embedded firmware storage.
For engineers reviewing the AT27BV010-15JC datasheet, AT27BV010-15JC pinout, AT27BV010-15JC application, or AT27BV010-15JC equivalent, key selection criteria include unregulated battery voltage support, OTP reliability in industrial temperature range (−40°C to +85°C), JEDEC-compliant PLCC mechanical compatibility, and Rapid™ programming algorithm validation for production programming throughput.
Technical Context
The AT27BV010-15JC implements a CMOS-based OTP memory array with two-line control (CE/OE), enabling bus contention avoidance in shared-data-bus architectures. Its dual-supply architecture allows seamless operation across 2.7–3.6 V (LVBO mode) and 4.5–5.5 V (TTL-compatible mode), with identical pinout and timing behavior across both ranges except for supply-dependent current draw and output drive strength.
Programming requires VCC = 6.5 V and VPP = 13.0 V, with a verified 100 µs PGM pulse width and up to 10 reprogramming attempts per byte. Product identification uses A9 = 12.0 V and A0 toggling to select manufacturer (0x1E) or device code (0x05), ensuring compatibility with industry-standard programmers calibrated for AT27C010.

FAQ
What is the maximum read access time specified for the AT27BV010-15JC?
The AT27BV010-15JC has a maximum read access time of 150 ns under all valid operating conditions - including VCC = 2.7–3.6 V and VCC = 4.5–5.5 V, at temperatures from −40°C to +85°C. This value is guaranteed across the full industrial temperature range and defines the minimum clock period for reliable data capture in synchronous interfaces.
Can the AT27BV010-15JC operate directly from an unregulated single-cell lithium battery?
Yes, the AT27BV010-15JC supports unregulated battery operation across 2.7–3.6 V without external regulation. Its LVBO-compatible I/O ensures TTL-level outputs at 3.0 V, and its <1 µA typical standby current minimizes drain on primary cells. The AT27BV010-15JC eliminates the need for voltage regulators in portable designs where supply ripple and dropout are concerns.
Is the AT27BV010-15JC pin-compatible with the AT27C010-15JC?
Yes, the AT27BV010-15JC uses identical 32-lead PLCC (32J) packaging and pinout as the AT27C010-15JC, including matching address, data, CE, OE, PGM, VCC, VPP, and GND assignments. This enables direct PCB-level replacement in existing designs, provided the system can accommodate the AT27BV010-15JC's dual-voltage capability and programming voltage requirements.
What programming voltage and sequence are required for the AT27BV010-15JC?
The AT27BV010-15JC requires VCC = 6.5 V ± 0.25 V and VPP = 13.0 V ± 0.25 V during programming, with VCC applied simultaneously with or before VPP. A 100 µs PGM pulse width is used, and a 0.1 µF ceramic capacitor must be placed between VPP and GND. The AT27BV010-15JC uses the same programming algorithm and equipment as the AT27C010.
Does the AT27BV010-15JC support product identification codes for automated programming?
Yes, the AT27BV010-15JC implements an Integrated Product Identification Code accessible via A9 = 12.0 V and A0 toggling, returning Manufacturer ID 0x1E and Device ID 0x05.
