Product details
Overview
AT27LV010A-70TU from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM optimized for low-voltage battery-powered systems, featuring 70 ns read access time, dual 3.0–3.6V or 4.5–5.5V supply operation, and industrial temperature range (−40°C to +85°C). It delivers TTL-compatible outputs at 3.0V and supports rapid programming at 100 µs/byte.
For engineers reviewing the AT27LV010A-70TU datasheet, AT27LV010A-70TU pinout, AT27LV010A-70TU application, or AT27LV010A-70TU equivalent, key selection criteria include its OTP architecture, JEDEC-standard PLCC/TSOP packaging, CMOS/TTL I/O compatibility, standby current <1 µA at 3.3V, and dual-voltage operational flexibility in embedded control and legacy system upgrades.
Technical Context
The AT27LV010A-70TU implements a two-line control interface (CE and OE) enabling bus contention avoidance in multi-device systems. Its Rapid Programming Algorithm uses 100 µs PGM pulses with verification loops per byte, requiring VCC = 6.5V and VPP = 13.0V during programming.
It features integrated product identification code (Manufacturer ID: 0x1E, Device ID: 0x05), accessed via A9 = 12.0V and A0 toggling - a function shared with AT27C010 and supported by standard programming equipment. Input/output levels meet LVTTL standards, and output drive capability is specified at 2.0 mA (VOL ≤ 0.4V) and −2.0 mA (VOH ≥ 2.4V) under 3.6V operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-70PU | 5V-only operation (4.5–5.5V); no 3.3V support; same 70 ns tACC and 32-pin PLCC/TSOP packages | Requires dedicated 5V rail; unsuitable for battery-powered or dual-voltage systems | Select when legacy 5V-only design mandates strict voltage compliance and no low-voltage operation needed |
| MX29LV160CBTI-70G | 16-Mbit 3V flash memory with 70 ns access; supports in-system reprogramming; different command set and pinout | Enables firmware updates in field; requires controller-side command sequencing and erase management | Select when field-upgradable code storage is required, accepting added software complexity and higher cost per bit |
Compared with AT27C010-70PU, the AT27LV010A-70TU adds 3.3V operation and lower standby power but retains identical programming compatibility and JEDEC pinout. Versus MX29LV160CBTI-70G, it offers simpler interface and guaranteed write-once integrity but lacks reprogrammability - ideal for fixed-function, cost-sensitive, or safety-critical firmware storage.

FAQ
What voltage ranges does the AT27LV010A-70TU support during normal read operation?
The AT27LV010A-70TU supports two distinct read supply ranges: 3.0V to 3.6V (low-voltage mode) and 4.5V to 5.5V (standard 5V ±10% mode). Both ranges deliver guaranteed 70 ns access time. During programming, however, it requires VCC = 6.5V and VPP = 13.0V - separate from read-mode supplies. The AT27LV010A-70TU maintains TTL-compatible output levels across both read ranges, enabling seamless integration into mixed-voltage systems.
Is the AT27LV010A-70TU pin-compatible with the AT27C010?
Yes, the AT27LV010A-70TU is pin-compatible and functionally compatible with the AT27C010 in all JEDEC-standard packages (32-lead PLCC, TSOP, VSOP). It shares identical pinout, control timing (tACC, tCE, tOE), programming algorithm, and product identification code (0x1E/0x05). The AT27LV010A-70TU extends compatibility by adding 3.3V operation while retaining full 5V-read functionality - making it a direct drop-in replacement in most AT27C010 designs.
What is the standby current specification for the AT27LV010A-70TU at 3.3V?
The AT27LV010A-70TU specifies a maximum standby current (ISB1) of 20 µA at VCC = 3.6V, with typical consumption less than 1 µA at 3.3V. This ultra-low quiescent draw is achieved through optimized CMOS design and is measured with CE = VCC ± 0.3V (CMOS-level disable). The AT27LV010A-70TU achieves this performance without compromising read speed or noise immunity, making it suitable for always-on battery-backed applications.
Does the AT27LV010A-70TU require external decoupling capacitors, and if so, what values?
Yes, the AT27LV010A-70TU requires two decoupling capacitors: a 0.1 µF high-frequency ceramic capacitor placed directly between VCC and GND, as close to the device pins as possible, and a 4.7 µF bulk electrolytic capacitor located near the power entry point for arrays of multiple devices. These values are mandated in the datasheet to suppress transient voltage excursions during CE switching and stabilize supply rails - failure to implement them may cause timing violations or device non-conformance. The AT27LV010A-70TU's internal design assumes this decoupling is present for reliable operation.
Can the AT27LV010A-70TU be programmed using standard EPROM programmers?
Yes, the AT27LV010A-70TU is fully compatible with industry-standard EPROM programmers designed for the AT27C010. It uses the same programming algorithm, voltage levels (VCC = 6.5V, VPP = 13.0V), and product identification code. The AT27LV010A-70TU programs identically - including the 100 µs PGM pulse width and verification loop - and is recognized automatically by programmers that support the AT27C010. No firmware or adapter modifications are required to program the AT27LV010A-70TU.
