Product details
Overview
AT27LV010A-70JU-T 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 delivers TTL-compatible outputs at 3.0 V, supports rapid programming at 100 µs/byte, and uses a JEDEC-standard 32-lead PLCC package for embedded memory applications in portable and dual-supply systems.
For engineers reviewing the AT27LV010A-70JU-T datasheet, AT27LV010A-70JU-T pinout, AT27LV010A-70JU-T application, or AT27LV010A-70JU-T equivalent, key selection criteria include low-voltage standby current (<1 µA typical at 3.3 V), CMOS/TTL I/O compatibility, JEDEC-standard PLCC footprint, and verified programming equivalence with AT27C010.
Technical Context
The AT27LV010A-70JU-T implements a two-line control architecture (CE and OE) enabling bus contention avoidance in multi-device memory systems. Its internal design supports simultaneous 3.3 V and 5 V host compatibility via voltage-tolerant inputs and TTL-level output drive at reduced supply.
Programming requires VCC = 6.5 V and VPP = 13.0 V with a 100 µs ±5% PGM pulse width, followed by verify-reprogram loops per byte. The integrated product identification code (0x1E/0x05) enables automatic algorithm selection in industry-standard programmers.

FAQ
What is the maximum read access time specification for AT27LV010A-70JU-T?
The AT27LV010A-70JU-T has a guaranteed maximum read access time of 70 ns when operated at VCC = 3.0–3.6 V and within the industrial temperature range. This timing applies to both address-to-output (tACC) and CE-to-output (tCE) delays, ensuring deterministic performance in real-time embedded systems. The "70" in the part number directly denotes this access speed grade.
Does AT27LV010A-70JU-T support true 3.3 V operation with TTL-compatible outputs?
Yes, the AT27LV010A-70JU-T produces TTL-compatible outputs (VOH ≥ 2.4 V, VOL ≤ 0.4 V) when VCC = 3.0 V, enabling direct interface with standard 5 V TTL logic without level-shifting circuitry. This is confirmed in the DC characteristics table for VCC = 3.0–3.6 V, where VOH is specified at IOH = −2.0 mA and VOL at IOL = 2.0 mA.
What programming voltage and conditions are required for AT27LV010A-70JU-T?
Programming the AT27LV010A-70JU-T requires VCC = 6.5 V ± 0.25 V and VPP = 13.0 V ± 0.25 V, with a 100 µs ±5% PGM pulse width. A 0.1 µF ceramic capacitor must be placed between VPP and GND. These conditions are mandatory per Table 5-6 and Figure 5-4; using incorrect voltages or missing decoupling risks incomplete programming or device damage.
Is AT27LV010A-70JU-T pin-compatible with AT27C010?
Yes, the AT27LV010A-70JU-T shares identical pinout, signal definitions, and 32-lead PLCC (32J) package with the AT27C010, as confirmed in the Pin Configurations section and Ordering Information table. Both devices use A0–A16, O0–O7, CE, OE, PGM, VPP, VCC, GND, and NC pins in the same physical locations and functional roles.
What is the standby current specification for AT27LV010A-70JU-T at 3.3 V?
The AT27LV010A-70JU-T specifies a maximum standby current (ISB1) of 20 µA at VCC = 3.6 V in CMOS mode (CE = VCC ± 0.3 V), with typical consumption less than 1 µA at 3.3 V. This ultra-low quiescent draw is validated in Table 5-3 and enables multi-year battery operation in always-on portable equipment.
