Product details
Overview
AT27BV4096-15JC from Atmel is a 4-Mbit (256K × 16) one-time programmable EPROM optimized for unregulated 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 44-lead PLCC packaging. It delivers TTL-compatible outputs at 3.0 V and supports rapid programming at 100 µs/word.
For engineers reviewing the AT27BV4096-15JC datasheet, AT27BV4096-15JC pinout, AT27BV4096-15JC application, or AT27BV4096-15JC equivalent, this device serves as a low-power, pin-compatible upgrade to AT27C4096 in portable microprocessor systems requiring stable 16-bit memory with battery-voltage tolerance and industrial temperature support.
Technical Context
The AT27BV4096-15JC implements a CMOS OTP EPROM architecture with two-line control (CE/OE), enabling bus contention avoidance in 16-bit data path systems. Its dual-supply compatibility allows seamless integration into mixed-voltage platforms-operating at 3.0 V while driving TTL-level loads, or at 5 V for legacy system compatibility.
It uses Atmel's Rapid™ Programming algorithm with 50 µs CE pulses and on-chip verification logic, requiring VPP = 13.0 V during programming and supporting integrated product identification via A9/VH and A0 toggling. Standby current remains below 20 µA at 3.6 V, and ESD protection exceeds 2,000 V per HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4,194,304-bit (256K × 16) OTP EPROM - enables full 16-bit instruction/data storage for embedded microcontrollers without refresh or write cycles |
| Read Access Time | 150 ns max at VCC = 2.7–3.6 V - meets timing budgets for 6.7 MHz bus interfaces in portable 16/32-bit systems |
| Supply Voltage Range | 2.7–3.6 V or 4.5–5.5 V - eliminates need for voltage regulation in battery-powered designs using Li-ion or alkaline cells |
| Standby Current | 20 µA max at VCC = 3.6 V - extends battery life in always-on or infrequently accessed memory applications |
| Programming Speed | 100 µs/word typical - reduces production programming time versus standard 5 V EPROMs while maintaining field-programmability |

Pinout & Package
AT27BV4096-15JC is housed in a 44-lead Plastic Leaded Chip Carrier (PLCC), JEDEC MS-018 AC compliant. Pin 1 is marked by corner notch; pins 1 and 23 are no-connect (NC) and must remain unconnected per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; A0–A17 must be driven with valid levels before CE/OE assertion |
| O0–O15 | Data Outputs | 16-bit bidirectional data bus in read mode; high-impedance when OE or CE is inactive |
| CE | Chip Enable | Active-low chip select; controls device activation and power state transition between active and standby modes |
| OE | Output Enable | Active-low output gate; enables data drive only when CE is also asserted, preventing bus contention |
| VCC | Power Supply | Main supply input (2.7–3.6 V or 4.5–5.5 V); requires local 0.1 µF ceramic decoupling capacitor |
| VPP | Programming Voltage | 13.0 V programming supply; must be applied simultaneously with or after VCC and removed simultaneously or before VCC |
| GND (×2) | Ground | Two dedicated ground pins (pins 22 and 44 in PLCC); both must be connected to system ground for signal integrity and EMI control |
| NC (×3) | No Connect | Pins 1, 23, and 39 in PLCC package - electrically isolated and must not be soldered or routed |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Voltage Read Operation | Operates natively at 2.7–3.6 V or 4.5–5.5 V - removes external regulators in battery-powered handheld devices and dual-host card products |

| Integrated Product ID Code | Manufacturer ID (001Eh) and Device Code (00F4h) accessible via A9/VH and A0 toggle - enables automatic algorithm selection in industry-standard programmers |
| JEDEC Pin Compatibility | Pinout matches AT27C4096 - allows drop-in replacement in existing 5 V designs without PCB revision or firmware changes |
| Low-Power CMOS Design | 20 µA max standby current at 3.6 V and 36 mW max active power at 5 MHz - extends runtime in portable instrumentation and medical monitors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C4096-15JC | 5 V-only operation (4.5–5.5 V); no 3 V support; identical pinout and timing | Lacks unregulated battery operation capability; requires regulated 5 V supply | Select when system already uses 5 V rail and no low-voltage flexibility is needed |
| MX29LV400CTTI-70G | Flash-based, 512 K × 8 organization; 70 ns access; 3.0 V core with 5 V I/O tolerance | Reprogrammable (not OTP); different data bus width and command-set interface | Select when firmware updates are required in-field; not suitable for true OTP security or cost-sensitive fixed-code deployments |
Compared with AT27C4096-15JC, the AT27BV4096-15JC adds battery-voltage operation and lower standby power but retains identical pinout and programming flow; versus MX29LV400CTTI-70G, it offers true OTP security and simpler interface but lacks reprogrammability and uses a 16-bit bus instead of 8-bit.

FAQ
What is the maximum read access time specified for AT27BV4096-15JC?
The AT27BV4096-15JC has a maximum read access time of 150 ns under all specified operating conditions (VCC = 2.7–3.6 V or 4.5–5.5 V, TA = -40°C to +85°C). This value is guaranteed across temperature and voltage ranges and applies to both CE- and OE-controlled read cycles, ensuring predictable timing for 16-bit microprocessor interfaces.
Can AT27BV4096-15JC operate directly from an unregulated 3.0 V lithium battery?
Yes, AT27BV4096-15JC is explicitly designed for unregulated battery operation across 2.7 V to 3.6 V, making it compatible with single-cell Li-ion (3.0–3.6 V) and multi-cell alkaline (3.0–4.5 V) sources. Its CMOS design maintains full functionality-including TTL-level outputs and 150 ns access-across this range without external regulation.
Is AT27BV4096-15JC pin-compatible with AT27C4096?
Yes, AT27BV4096-15JC is JEDEC-pin-compatible with AT27C4096, sharing identical 44-lead PLCC pinout, address/data bus mapping, and control signal assignments (CE, OE, VCC, GND). This allows direct substitution in existing 5 V designs, provided VPP programming voltage (13.0 V) and sequencing requirements are met.
What programming voltage and sequence does AT27BV4096-15JC require?
AT27BV4096-15JC requires VPP = 13.0 ± 0.25 V and VCC = 6.5 ± 0.25 V during programming, with VCC applied simultaneously with or before VPP and removed simultaneously or after VPP. The Rapid™ algorithm uses 50 µs CE pulses and internal verification; standard EPROM programmers supporting AT27C4096 can program AT27BV4096-15JC with updated voltage settings.
Does AT27BV4096-15JC support industrial temperature range operation?
Yes, AT27BV4096-15JC is qualified for industrial temperature operation from -40°C to +85°C, as confirmed by the "I" suffix in ordering codes (e.g., AT27BV4096-15JI) and verified in the DC/AC characteristics tables. All key parameters-including 150 ns access time, standby current, and output drive-are guaranteed across this full range.
