Product details
Overview
AT27LV010A-70JU from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM with 70 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, JEDEC-standard 32-lead PLCC packaging, and rapid 100 µs/byte programming - ideal for battery-powered portable systems requiring low-power nonvolatile storage.
For engineers reviewing the AT27LV010A-70JU datasheet, AT27LV010A-70JU pinout, AT27LV010A-70JU application, or AT27LV010A-70JU equivalent, key selection criteria include its dual-supply compatibility, sub-1 µA typical standby current at 3.3 V, TTL-level output drive at 3.0 V, and JEDEC-standard PLCC footprint for legacy system upgrades and embedded boot memory.
Technical Context
The AT27LV010A-70JU implements a standard OTP EPROM architecture with two-line control (CE/OE), supporting fast random-access reads and rapid byte-wise programming using VPP = 13.0 V and VCC = 6.5 V. Its internal design enables TTL-compatible outputs even when powered from 3.0 V, eliminating level-shifting in mixed-voltage systems.
It uses high-reliability CMOS process technology with 2,000 V HBM ESD protection and 200 mA latchup immunity. The integrated product identification code (0x1E/0x05) ensures compatibility with industry-standard programmers and guarantees identical programming behavior to the AT27C010.

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 | 5 V only operation (4.5–5.5 V); no 3.0–3.6 V support; identical 70 ns access and PLCC-32 package | Requires dedicated 5 V rail; unsuitable for battery-powered or dual-voltage systems | Select when legacy 5 V infrastructure exists and low-voltage operation is unnecessary |
| MX27C1000PC-12 | 120 ns access time; 5 V only; 32-pin PDIP package; no integrated ID code or rapid programming | Larger footprint, slower timing, and manual programming setup increase integration effort | Select only if cost is primary constraint and timing margin exceeds 120 ns |
Compared with AT27C010-70PU and MX27C1000PC-12, the AT27LV010A-70JU uniquely delivers dual-voltage operation, sub-1 µA standby, and rapid 100 µs/byte programming - making it optimal for portable, industrial, and upgrade applications where power, flexibility, and production efficiency matter.

FAQ
What is the maximum operating voltage for AT27LV010A-70JU during normal read operation?
The AT27LV010A-70JU supports two read voltage ranges: 3.0 V to 3.6 V (low-voltage mode) and 4.5 V to 5.5 V (standard 5 V mode). It does not operate at voltages outside these ranges during read. VPP = 13.0 V is required only during programming, not read mode. The AT27LV010A-70JU must never be subjected to VCC > 5.5 V or < 3.0 V in active or standby states.
Is AT27LV010A-70JU pin-compatible with AT27C010?
Yes, the AT27LV010A-70JU is fully pin-compatible with the AT27C010 in the 32-lead PLCC package. Both share identical pin functions, layout, and mechanical dimensions. The AT27LV010A-70JU retains the same CE/OE/PGM control scheme and address/data bus mapping, enabling direct PCB replacement without layout changes - provided VPP and decoupling are verified per the AT27LV010A-70JU datasheet.
Does AT27LV010A-70JU require external VPP switching circuitry during programming?
Yes, the AT27LV010A-70JU requires an external circuit to apply VPP = 13.0 V ± 0.25 V during programming, while maintaining VCC = 6.5 V ± 0.25 V. A 0.1 µF capacitor must be placed between VPP and GND per the datasheet. Standard EPROM programmers with VPP switching capability (e.g., BP Microsystems, Xeltek) support the AT27LV010A-70JU natively due to its integrated ID code and rapid programming algorithm.
What is the meaning of the 'JU' suffix in AT27LV010A-70JU?
The 'JU' suffix in AT27LV010A-70JU denotes the 32-lead plastic J-leaded chip carrier (PLCC) package with matte tin lead finish and industrial temperature range (−40°C to +85°C). The '70' indicates 70 ns maximum access time. 'JU' is Atmel's ordering code for green (Pb/halide-free), JEDEC-compliant PLCC devices - distinct from 'PU' (PDIP) or 'TU' (TSOP) variants.
Can AT27LV010A-70JU outputs drive standard TTL inputs when powered from 3.0 V?
Yes, the AT27LV010A-70JU produces TTL-compatible outputs when powered from 3.0 V: VOH ≥ 2.4 V (at IOH = −2.0 mA) and VOL ≤ 0.4 V (at IOL = 2.0 mA). This allows direct interfacing with standard 5 V TTL logic without level shifters - a key design advantage confirmed in the DC characteristics table for VCC = 3.0–3.6 V operation. This behavior is explicitly guaranteed in the AT27LV010A-70JU datasheet.
