Product details
Overview
AT27LV010A-15JI from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM with 150 ns read access time, dual-voltage operation (3.0–3.6 V or 4.5–5.5 V), and industrial temperature range (−40°C to +85°C). It features CMOS/TTL-compatible I/O, 20 µA max standby current at 3.6 V, and JEDEC-standard 32-lead PLCC packaging - used in embedded boot memory, legacy industrial controllers, and battery-powered instrumentation.
For engineers reviewing the AT27LV010A-15JI datasheet, AT27LV010A-15JI pinout, AT27LV010A-15JI application, or AT27LV010A-15JI equivalent, key selection criteria include read timing consistency across voltage ranges, OTP reliability for firmware storage, low-power standby behavior, and compatibility with standard EPROM programmers and 5V/3.3V mixed-signal systems.
Technical Context
The AT27LV010A-15JI implements a single-supply OTP EPROM architecture with two-line control (CE/OE), enabling bus contention avoidance in shared-memory systems. Its Rapid™ programming algorithm uses 100 µs/byte pulses at VCC = 6.5 V and VPP = 13.0 V, with integrated product identification code (0x1E/0x05) for automated programmer recognition.
It supports TTL-level outputs at 3.0 V, ensuring interoperability with 5 V logic without level shifters. The device operates in five distinct modes - Read, Output Disable, Standby, Rapid Program, and Product Identification - each defined by specific CE/OE/PGM voltage combinations and VPP state, with absolute maximum ratings including ±2.0 V on all pins and +14.0 V on A9 during ID access.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,048,576-bit (128K × 8) OTP EPROM - fixed boot code storage with no reprogrammability after initial programming. |
| Read Access Time | 150 ns max at VCC = 3.0–3.6 V or 4.5–5.5 V - defines minimum clock cycle for reliable data fetch in microcontroller boot sequences. |
| Supply Voltage Range | 3.0–3.6 V or 4.5–5.5 V - enables drop-in use in both 3.3 V portable systems and legacy 5 V industrial backplanes. |
| Standby Current | 20 µA max at VCC = 3.6 V (CMOS CE input) - ensures ultra-low power retention in battery-backed applications. |
| Programming Voltage | VPP = 13.0 ± 0.25 V required during programming - mandates dedicated high-voltage supply or programmer support, not compatible with standard 5 V-only systems. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade deployment in motor drives, PLCs, and outdoor telemetry hardware. |
| Package Type | 32-lead PLCC (32J) - surface-mountable, socket-compatible, and JEDEC MS-016 AE compliant for legacy board reuse. |
Pinout & Package
AT27LV010A-15JI is housed in a 32-lead Plastic Leaded Chip Carrier (PLCC), JEDEC MS-016 AE compliant, with 0.050" pitch and body size 1.14 × 1.14 inches (29.0 × 29.0 mm). Pin 1 is marked by index notch and corner chamfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; driven by CPU or controller during read/program cycles. |
| O0–O7 | Data Outputs | 8-bit bidirectional data bus in read mode; high-impedance when OE or CE inactive - prevents bus contention. |
| CE | Chip Enable | Active-low chip select; controls device activation and entry into Standby mode when high - critical for power gating. |
| OE | Output Enable | Active-low output gate; decouples data bus without disabling internal logic - enables multi-device sharing of same data lines. |
| PGM | Program Strobe | Active-low programming trigger; initiates byte programming pulse only when CE = low and VPP = 13 V - prevents accidental writes. |
| VCC | Power Supply | Primary supply (3.0–3.6 V or 4.5–5.5 V); must be applied before/with VPP and removed after/with VPP per sequencing requirement. |
| VPP | Programming Voltage | 13.0 V programming supply; internally isolated during read mode - requires external HV source or dedicated programmer. |
| GND | Ground Reference | Common return path for VCC and VPP; requires local 0.1 µF ceramic decoupling per device per datasheet system guidelines. |
| NC | No Connect | Unbonded pin (A12 in TSOP/VSOP top view, A14 in PLCC top view) - must remain unconnected to avoid noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rapid™ Programming Algorithm | 100 µs/byte typical programming time with up to 10 retry pulses per byte - reduces production programming cycle time vs. conventional EPROMs. |
| Integrated Product ID Code | Manufacturer ID = 0x1E, Device ID = 0x05 - enables automatic algorithm selection in industry-standard programmers (e.g., BP Microsystems, Xeltek). |
| Dual-Voltage Read Operation | Valid read functionality at either 3.3 V or 5 V supply - eliminates need for voltage translators in mixed-supply systems like PC card adapters. |
| JEDEC-Compatible I/O Levels | TTL-compatible outputs at 3.0 V, CMOS/TTL inputs - ensures direct interface with 74LS, 74HC, and microcontroller GPIO without level-shifting circuitry. |
| High-Reliability Process | 2,000 V HBM ESD rating and 200 mA latchup immunity - suitable for manufacturing environments and field-deployed industrial equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-15JC | 5 V-only operation (4.5–5.5 V); no 3.3 V support; identical 150 ns timing and PLCC package. | Requires dedicated 5 V rail; unsuitable for battery-powered or dual-voltage systems. | Select when legacy 5 V infrastructure prohibits voltage scaling and lower power is not required. |
| MX29LV160CBTI-70G | 16 Mbit Flash (2M × 8), 70 ns access, 3.0–3.6 V only, 48-pin TSOP; supports erase/write cycles. | Reprogrammable; requires command sequence and sector management; higher density but different interface protocol. | Choose for field-upgradable firmware where OTP permanence is not mandatory and board layout accommodates larger package. |
Compared with AT27C010-15JC, the AT27LV010A-15JI adds 3.3 V operation and cuts standby current by >90%, while retaining pinout and programming compatibility; versus MX29LV160CBTI-70G, it offers simpler interface and OTP security but lacks reprogrammability and requires separate high-voltage programming hardware.

FAQ
What is the guaranteed read access time for AT27LV010A-15JI?
The AT27LV010A-15JI guarantees a maximum read access time of 150 ns under all specified operating conditions - including VCC = 3.0–3.6 V or 4.5–5.5 V, and temperature range −40°C to +85°C. This value is fully tested and specified in the AC Characteristics table, making it suitable for systems with tight timing budgets such as real-time controllers and legacy CPU boot sequences.
Does AT27LV010A-15JI support true 3.3 V operation with TTL-compatible outputs?
Yes, the AT27LV010A-15JI delivers TTL-compatible output levels (VOH ≥ 2.4 V, VOL ≤ 0.4 V) when operated at VCC = 3.0 V, enabling direct interfacing with standard 5 V TTL logic without level shifters. This behavior is explicitly verified in the DC Operating Characteristics table and confirmed in the "System Considerations" section of the datasheet.
Can AT27LV010A-15JI be programmed using standard EPROM programmers?
Yes, the AT27LV010A-15JI is programming-compatible with the AT27C010 and uses the same industry-standard programming equipment. Its integrated product identification code (0x1E/0x05) allows automatic algorithm detection, and it follows the Rapid™ programming protocol with 100 µs pulses at VPP = 13.0 V - supported by BP Microsystems, Xeltek, and Data I/O programmers with LV EPROM profiles.
What is the purpose of the PGM pin on AT27LV010A-15JI?
The PGM pin on AT27LV010A-15JI is an active-low program strobe that initiates byte programming when asserted (low) along with CE = low and VPP = 13.0 V. It is not used during read operations. The pin must remain high (or NC) in normal system operation to prevent accidental programming - a critical safety feature for deployed firmware storage.
Is AT27LV010A-15JI pin-compatible with AT27C010-15JC?
Yes, the AT27LV010A-15JI is pin-compatible with the AT27C010-15JC in the 32-lead PLCC package (32J), sharing identical pin functions, placement, and mechanical footprint. Both devices support the same address/data/control signals and JEDEC-standard timing - enabling direct substitution where 3.3 V operation and lower power are acceptable.
