Product details
Overview
AT27LV010A-12JC from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM optimized for low-voltage battery-powered systems, featuring 120 ns read access time at 3.0–3.6 V or 4.5–5.5 V, dual-supply compatibility, and JEDEC-standard PLCC-32 packaging. It delivers TTL/CMOS-compatible I/O, <1 µA typical standby current, and Rapid™ programming at 100 µs/byte.
For engineers reviewing the AT27LV010A-12JC datasheet, AT27LV010A-12JC pinout, AT27LV010A-12JC application, or AT27LV010A-12JC equivalent, this page provides verified package mapping, confirmed OTP EPROM functionality, JEDEC-compliant timing and voltage specs, and real-world system integration guidance for portable, industrial, and legacy-compatible embedded designs.
Technical Context
The AT27LV010A-12JC operates as a non-volatile memory device with two-line control (CE/OE), supporting both 3.3 V and 5 V read modes while maintaining TTL-level output compatibility across supply ranges. Its architecture enables byte-level random access with no internal refresh or write cycles during read operation.
It implements Atmel's Rapid™ Programming Algorithm requiring VCC = 6.5 V and VPP = 13.0 V for programming, with integrated product identification code (Manufacturer ID: 0x1E, Device ID: 0x05) accessible via A9/VH and A0 toggling. The device uses standard EPROM cell technology with 2,000 V ESD protection and 200 mA latchup immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,048,576-bit (128K × 8) OTP EPROM - fixed content storage without reprogrammability after initial programming. |
| Read Access Time | 120 ns max at VCC = 3.0–3.6 V or 4.5–5.5 V - defines minimum address-to-data valid delay in high-speed microcontroller boot or firmware fetch paths. |
| Supply Voltage Range | 3.0–3.6 V or 4.5–5.5 V - enables direct integration into dual-rail systems (e.g., 3.3 V logic with 5 V legacy peripherals) without level shifters. |
| Standby Current | 20 µA max (CMOS CE mode) at VCC = 3.6 V - supports ultra-low-power sleep states in portable instrumentation and remote sensors. |
| Active Power Dissipation | 29 mW max at 5 MHz and VCC = 3.6 V - reduces thermal load and extends battery life compared to standard 5 V EPROMs consuming >100 mW. |
| Programming Speed | 100 µs/byte typical with Rapid™ algorithm - cuts firmware update time by >5× versus conventional EPROM programmers. |
| Input/Output Compatibility | JEDEC LVTTL-compliant inputs and outputs - ensures plug-and-play interoperability with 3.3 V and 5 V microcontrollers, FPGAs, and ASICs. |
Pinout & Package
AT27LV010A-12JC is supplied in a 32-lead Plastic Leaded Chip Carrier (PLCC) package per JEDEC MS-016 AE, with lead pitch of 1.27 mm and body size 18.5 × 18.5 mm. Pin 1 is marked by an index notch on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus accepting 0–131,071 (128K) locations; CMOS/TTL compatible with VIH ≥ 2.0 V and VIL ≤ 0.8 V. |
| O0–O7 | Data Outputs | 8-bit bidirectional data bus in read mode; high-impedance when OE or CE inactive; VOL ≤ 0.4 V at 2.0 mA sink. |
| CE | Chip Enable | Active-low chip select; controls device activation and power state - VIH ≥ 2.0 V disables outputs and enters standby. |
| OE | Output Enable | Active-low output gate; allows shared bus operation without contention when CE is asserted but OE is deasserted. |
| PGM | Program Strobe | Active-low programming control signal; requires VPP = 13.0 V and precise 95–105 µs pulse width during byte programming. |
| VCC | Power Supply | Main supply input for read/standby (3.0–3.6 V or 4.5–5.5 V); must be applied simultaneously with or before VPP during programming. |
| VPP | Programming Voltage | 13.0 V ± 0.25 V programming supply; internally routed to oxide-breakdown circuitry; requires 0.1 µF bypass capacitor to ground. |
| GND | Ground Reference | Common return path for VCC, VPP, and I/O; decoupling capacitors (0.1 µF ceramic + 4.7 µF bulk) required per datasheet layout rules. |
| NC | No Connect | Pin 6 (PLCC top view) is unconnected - must remain floating; not usable for routing or grounding. |

FAQ
What is the maximum read access time specified for the AT27LV010A-12JC?
The AT27LV010A-12JC has a maximum read access time of 120 ns under all supported supply conditions (3.0–3.6 V or 4.5–5.5 V) and operating temperatures (0°C to 70°C). This value is guaranteed across the commercial temperature range and reflects the worst-case propagation delay from address stabilization to valid data on O0–O7 pins when both CE and OE are asserted.
Does the AT27LV010A-12JC support true 3.3 V operation with TTL-compatible outputs?
Yes, the AT27LV010A-12JC produces TTL-level outputs (VOH ≥ 2.4 V, VOL ≤ 0.4 V) when operated at VCC = 3.0–3.6 V, ensuring direct interface with standard 5 V TTL logic without level-shifting circuitry. This behavior is explicitly validated in the datasheet's DC characteristics table for both 3.3 V and 5 V supply conditions.
Can the AT27LV010A-12JC be programmed using standard EPROM programmers?
The AT27LV010A-12JC programs identically to the AT27C010 and uses the same programming equipment, including standard EPROM programmers capable of supplying VPP = 13.0 V and generating 100 µs PGM pulses. Its integrated product identification code (0x1E/0x05) allows modern programmers to auto-configure correct voltages and algorithms.
What is the purpose of the NC pin on the AT27LV010A-12JC PLCC package?
Pin 6 on the AT27LV010A-12JC PLCC package is designated NC (No Connect) and must remain electrically unconnected - it serves no internal function and is not bonded to the die. Routing traces to or grounding this pin violates the datasheet layout requirements and may compromise device reliability or signal integrity.
How does the Rapid™ programming algorithm improve production efficiency for the AT27LV010A-12JC?
The Rapid™ programming algorithm reduces average programming time to ~100 µs per byte by combining single-pulse programming with immediate verify-reprogram loops per address. This eliminates batch verification delays and enables real-time pass/fail feedback during production, cutting total 128K-byte programming time to under 15 seconds versus >2 minutes for conventional EPROM algorithms.
