Product details
Overview
AT27C010L-15JC from Atmel is a 128K × 8-bit (1 Mbit) one-time programmable EPROM with 150 ns maximum read access time, 5 V ±10% supply operation, and low-power CMOS design consuming ≤25 mA active current at 5 MHz and ≤100 µA standby current. It features dual-line control (CE/OE), rapid programming (100 µs/byte), and JEDEC-standard 32-lead PLCC packaging for embedded firmware storage in microprocessor systems.
For engineers reviewing the AT27C010L-15JC datasheet, AT27C010L-15JC pinout, AT27C010L-15JC application, or AT27C010L-15JC equivalent, key selection criteria include read timing (tACC = 150 ns), low ICC/ISB trade-offs between AT27C010 and AT27C010L variants, VPP programming voltage (12.0 V ±0.5 V), and compatibility with industry-standard EPROM programmers supporting Integrated Product Identification Code.
Technical Context
The AT27C010L-15JC implements a standard OTP EPROM architecture with address decoding for A0–A16, eight bidirectional data outputs (O0–O7), and separate chip enable (CE) and output enable (OE) controls to prevent bus contention. Its Rapid™ programming algorithm uses 100 µs PGM pulses with verification loops per byte under 13.0 V VPP and 6.5 V VCC conditions.
It supports three operating modes-Read, Standby, and Rapid Program-with distinct CE/OE/PGM logic combinations and voltage thresholds. The device includes integrated product identification (A9 = 12.0 V for Manufacturer ID, A0 toggled for Device Code) and meets 2000 V ESD and 200 mA latchup immunity specifications per JEDEC standards.
Key Specifications

|---|---|
| Memory Size | 128K × 8 bits (1,048,576 bits); provides full firmware image storage for 8-bit microcontrollers without external memory expansion. |
| Read Access Time | 150 ns max (tACC); eliminates WAIT states in 6–8 MHz Z80, 8051, or 68K-based systems operating at ≤6.67 MHz. |
| VCC Supply | 5 V ±10%; compatible with standard TTL/CMOS logic rails and eliminates need for auxiliary voltage regulators. |
| Active Current | 25 mA max at 5 MHz; enables low-heat dissipation in dense PCB layouts with multiple EPROMs. |
| Standby Current | 100 µA max (ISB1, CMOS CE); supports battery-backed or low-power sleep modes in industrial controllers. |

Pinout & Package
AT27C010L-15JC is housed in a 32-lead Plastic J-Leaded Chip Carrier (PLCC), JEDEC MS-016 AE compliant, with 1.27 mm pitch, 20.2 × 20.2 mm body, and gull-wing leads suitable for surface-mount reflow or socketed prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus interface; selects one of 131,072 bytes; A16 is MSB for full 128K addressing. |
| O0–O7 | Data Outputs | 8-bit unidirectional data bus during read mode; high-impedance when OE or CE inactive. |
| CE | Chip Enable | Active-low global select; disables outputs and reduces ICC to ISB when high; used for memory banking. |
| OE | Output Enable | Active-low output gate; allows shared data bus usage with other peripherals without bus contention. |
| PGM | Program Strobe | Active-low pulse input (100 µs width) that initiates byte programming when VPP = 12 V and address valid. |
| VPP | Programming Voltage | 12.0 V ±0.5 V input required only during programming; must be applied after VCC and removed before VCC. |
| VCC | Power Supply | +5 V ±10% main supply; powers logic and output drivers; decoupling capacitor (0.1 µF ceramic) required at pin. |
| GND | Ground | Reference return path for all signals and supplies; requires low-inductance connection to system ground plane. |
| NC | No Connect | Unbonded internal pad; must remain floating-no external connection permitted. |

FAQ
What is the maximum read access time specified for the AT27C010L-15JC?
The AT27C010L-15JC has a maximum read access time (tACC) of 150 ns under commercial temperature conditions (0°C to 70°C) with VCC = 5 V ±10%. This value is guaranteed across all operating voltages and load conditions defined in the datasheet, and directly determines whether WAIT states are needed in host microprocessor interfaces.
Does the AT27C010L-15JC require a separate programming voltage supply?
Yes, the AT27C010L-15JC requires VPP = 12.0 V ±0.5 V applied to pin 1 during programming. This voltage must be stable, noise-free, and sequenced after VCC application and before VCC removal. The AT27C010L-15JC cannot be programmed using only the 5 V VCC rail - attempting so will result in incomplete or corrupted data writes.
Can the AT27C010L-15JC be used as a direct replacement for the AT27C010-15JC?
The AT27C010L-15JC is pin-compatible and functionally identical to the AT27C010-15JC except for reduced active current (25 mA vs. 35 mA). No PCB changes are required, but system-level power budgeting must verify that the lower ICC does not affect voltage regulator stability or shared rail behavior in multi-device configurations.
How is the Integrated Product Identification Code accessed on the AT27C010L-15JC?
The AT27C010L-15JC's identification code is read by asserting A9 = 12.0 V (VH) while holding A1–A16 = VIL and toggling A0 between VIL (for Manufacturer ID = 0x1E) and VIH (for Device Code = 0x05). This mode activates only during read operation with CE = OE = VIL and is supported by all industry-standard EPROM programmers.
What decoupling capacitance is required for stable operation of the AT27C010L-15JC?
A 0.1 µF ceramic capacitor must be placed between VCC and GND pins of the AT27C010L-15JC, located as close as possible to the device. For boards with multiple AT27C010L-15JC devices, an additional 4.7 µF bulk electrolytic capacitor should be added near the power entry point to suppress array-level supply ripple and transient coupling.
