Product details
Overview
AT27LV010A-70JC 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 JEDEC-standard PLCC-32 packaging. It serves as nonvolatile program storage in battery-powered portable systems, embedded controllers, and legacy industrial firmware modules requiring low-power standby and TTL/CMOS compatibility.
For engineers reviewing the AT27LV010A-70JC datasheet, AT27LV010A-70JC pinout, AT27LV010A-70JC application, or AT27LV010A-70JC equivalent, key selection criteria include its 70 ns tACC at 3.3 V, <1 µA typical standby current, rapid 100 µs/byte programming, integrated product identification code, and support for both 3.3 V and 5 V host interfaces without level-shifting.
Technical Context
The AT27LV010A-70JC implements a standard OTP EPROM architecture with two-line control (CE/OE), enabling bus contention avoidance in shared-memory systems. Its address space spans A0–A16 (17-bit), supporting full 128K-byte decoding, and features dedicated PGM and VPP pins for high-voltage programming at 13.0 V.
It operates in five distinct modes-Read, Output Disable, Standby, Rapid Program, and Product Identification-each defined by specific CE/OE/PGM logic states and voltage conditions. The device guarantees reliable programming via Atmel's Rapid™ algorithm and includes on-chip ESD protection (2,000 V) and latchup immunity (200 mA).

IC Role / Device Role / Timing Role: Nonvolatile program memory holding boot loader and signal processing routines; accessed only during startup or firmware update. Use Value: 70 ns access time enables fast initialization, while <1 µA standby current extends single-battery operation beyond 12 months. |
Use Scenario: Fixed-function programmable logic controllers deployed in factory automation where firmware updates are infrequent but reliability is critical. IC Role / Device Role / Timing Role: One-time programmable ROM storing ladder logic interpreter and I/O configuration tables; immune to accidental overwrite. Use Value: 2,000 V ESD protection and -40°C to +85°C industrial temperature rating ensure robustness in electrically noisy plant-floor environments. |
| Legacy Embedded Instrumentation | Telecom Line Card Boot Memory |
Use Scenario: Retrofit of aging test equipment where original EPROMs are obsolete and board layout cannot accommodate new packages. IC Role / Device Role / Timing Role: Drop-in replacement for AT27C010 in 32-pin PLCC sockets; identical pinout and JEDEC timing compliance. Use Value: Full compatibility with existing programming hardware and 5 V system buses eliminates redesign cost and qualification delays. |
Use Scenario: Modular telecom line cards requiring secure, tamper-resistant boot code storage independent of volatile RAM or flash wear-out concerns. IC Role / Device Role / Timing Role: Primary boot ROM executing initial hardware self-test and loading of DSP firmware from secondary storage. Use Value: Rapid™ programming enables efficient field-replaceable module provisioning, and 13.0 V VPP isolation prevents accidental corruption during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-70PC | 5 V only (4.5–5.5 V), no 3.3 V operation; same 70 ns speed, PLCC-32 package | Requires dedicated 5 V rail; incompatible with battery-powered 3.3 V systems | Select when legacy 5 V infrastructure prohibits voltage scaling and PGM/VPP sequencing is already implemented |
| MX27C1000-70PC | 5 V only, 70 ns access, PLCC-32; higher ICC active current (35 mA vs. 8 mA at 5 MHz) | Lacks dual-voltage support and integrated ID code; not Rapid™ programmable | Choose only if cost sensitivity outweighs power/performance trade-offs and programming ecosystem supports non-Rapid algorithms |
Compared with AT27LV010A-70JC, AT27C010-70PC offers identical timing and footprint but sacrifices low-voltage flexibility, while MX27C1000-70PC lacks both voltage adaptability and programming efficiency-making AT27LV010A-70JC the optimal choice for new designs requiring 3.3 V compatibility, ultra-low standby, and rapid production programming.

FAQ
What is the maximum operating temperature range for the AT27LV010A-70JC?
The AT27LV010A-70JC is rated for industrial temperature operation from -40°C to +85°C. This specification is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet. The "I" suffix in ordering codes (e.g., AT27LV010A-70JI) denotes industrial grade, and the -70JC variant shares this extended range. AT27LV010A-70JC maintains full electrical performance-including 70 ns access time and <1 µA standby current-across this entire range.
Does the AT27LV010A-70JC require a separate programming voltage supply?
Yes, the AT27LV010A-70JC requires VPP = 13.0 ± 0.25 V applied to the VPP pin during programming, while VCC is held at 6.5 ± 0.25 V. This high-voltage supply is mandatory for oxide breakdown programming and is not used during read or standby modes. The datasheet specifies strict sequencing: VCC must be applied simultaneously with or before VPP, and removed simultaneously with or after VPP. AT27LV010A-70JC cannot be programmed using only VCC.
Is the AT27LV010A-70JC pin-compatible with the AT27C010?
Yes, the AT27LV010A-70JC is fully pin-compatible with the AT27C010 across all JEDEC-standard packages, including PLCC-32. Pin functions (A0–A16, O0–O7, CE, OE, PGM, VPP, VCC, GND) match identically, and the AC timing parameters (tACC, tCE, tOE) are aligned for drop-in replacement in existing 5 V designs. The AT27LV010A-70JC datasheet explicitly states JEDEC compatibility and identical programming methodology with the AT27C010.
What decoupling capacitance is required for stable operation of the AT27LV010A-70JC?
The AT27LV010A-70JC requires a minimum 0.1 µF high-frequency ceramic capacitor connected between VCC and GND, placed as close to the device pins as possible. For systems with multiple EPROMs or high-noise environments, a bulk 4.7 µF electrolytic capacitor should also be added near the power entry point. These values are specified in the "System Considerations" section of the datasheet to suppress transient excursions caused by CE switching and ensure reliable read/write margins.
Can the AT27LV010A-70JC be used in a 3.3 V system interfacing with 5 V logic?
Yes, the AT27LV010A-70JC produces TTL-level outputs (VOH ≥ 2.4 V, VOL ≤ 0.4 V) when operated at VCC = 3.0–3.6 V, making it directly compatible with standard 5 V TTL inputs. Its VIH threshold (≥ 2.0 V) and VIL threshold (≤ 0.8 V) also accept 5 V logic signals without damage. This dual-voltage interoperability is a core design feature documented in the "Description" and "DC Operating Characteristics" sections of the AT27LV010A-70JC datasheet.
