Product details
Overview
AT27LV010A-15TI 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 at 3.0–3.6 V or 4.5–5.5 V, 20 µA max standby current, and JEDEC-standard 32-lead TSOP packaging. It serves as nonvolatile program storage in embedded controllers and legacy BIOS modules.
For engineers reviewing the AT27LV010A-15TI datasheet, AT27LV010A-15TI pinout, AT27LV010A-15TI application, or AT27LV010A-15TI equivalent, key selection criteria include dual-voltage operation compatibility, rapid 100 µs/byte programming, TTL/CMOS I/O compatibility, and industrial temperature support (−40°C to +85°C).
Technical Context
The AT27LV010A-15TI implements a standard OTP EPROM architecture with two-line control (CE/OE), supporting both 3.3 V and 5 V read modes without level-shifting. Its Rapid™ programming algorithm uses 100 µs PGM pulses at VCC = 6.5 V and VPP = 13.0 V, with built-in verification loops per byte.
It features integrated product identification (Manufacturer ID = 0x1E, Device ID = 0x05) accessed via A9 = 12.0 V and A0 toggling, enabling automatic algorithm selection in industry-standard programmers. All I/O pins meet LVTTL voltage thresholds and tolerate −2.0 V to +7.0 V transients (≤20 ns).

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 (4.5–5.5 V), no low-voltage mode; identical 150 ns speed and 32-lead PLCC package. | Requires dedicated 5 V rail; unsuitable for battery-powered or mixed-voltage systems. | Select when legacy 5 V design prohibits voltage scaling and PLCC mounting is preferred. |
| MX27C1000-15PC | 5 V only, 32-pin PDIP package; 150 ns speed but lacks Rapid™ programming and product ID code. | Targeted at through-hole prototyping or repair; no TSOP option or industrial temp grade. | Select for hand-soldered development boards where surface-mount constraints do not apply. |
Compared with AT27C010-15JC and MX27C1000-15PC, the AT27LV010A-15TI uniquely supports dual-voltage operation and rapid programming while maintaining pin-compatible TSOP packaging - enabling lower system power, faster production, and seamless upgrade paths in industrial and telecom platforms.

FAQ
What is the maximum read access time specified for the AT27LV010A-15TI?
The AT27LV010A-15TI has a maximum read access time of 150 ns under both 3.0–3.6 V and 4.5–5.5 V supply conditions. This value is guaranteed across the full industrial temperature range (−40°C to +85°C) and defines the minimum time between address valid and valid data appearing on O0–O7. The "15" in the part number directly references this 150 ns speed grade.
Does the AT27LV010A-15TI support true 3.3 V operation without level shifters?
Yes, the AT27LV010A-15TI operates fully at 3.0–3.6 V with TTL-compatible outputs - it drives VOH ≥ 2.4 V at IOH = −400 µA and VOL ≤ 0.4 V at IOL = 2.1 mA under 3.3 V conditions. This eliminates need for external level translators when interfacing with 3.3 V microcontrollers or FPGAs, unlike 5 V-only EPROMs such as the AT27C010.
Can the AT27LV010A-15TI be programmed using standard EPROM programmers?
Yes, the AT27LV010A-15TI uses the same programming protocol and pinout as the AT27C010, including identical VPP = 13.0 V requirement and Rapid™ 100 µs/byte algorithm. Industry-standard programmers with AT27C010 support can program the AT27LV010A-15TI without firmware updates, provided they supply correct VCC (6.5 V) and VPP (13.0 V) during programming.
What package type does the AT27LV010A-15TI use, and is it RoHS compliant?
The AT27LV010A-15TI uses a 32-lead TSOP (8 × 20 mm, JEDEC MO-142 BD) package. While the original Atmel datasheet predates RoHS enforcement, this TSOP variant was manufactured with lead-free terminations in later production lots; full RoHS compliance documentation is available upon request for specific date codes shipped by Aetrix Electronics.
How does the standby current of the AT27LV010A-15TI compare to 5 V EPROMs?
The AT27LV010A-15TI draws ≤20 µA max standby current at VCC = 3.6 V, which is less than one-fifth the typical standby draw of comparable 5 V EPROMs (e.g., AT27C010 draws ~100 µA). This reduction directly extends battery life in portable applications and lowers system-level thermal load in dense memory arrays.
