Product details
Overview
AT27C010L-15PI from Atmel is a 128K × 8-bit one-time programmable EPROM (OTP EPROM) with 45 ns read access time, 5V ±10% supply operation, and industrial temperature range (−40°C to +85°C). It features CMOS/TTL-compatible I/O, 100 µA max standby current, and Rapid™ programming at 100 µs/byte - enabling fast firmware storage in microprocessor-based embedded control systems.
For engineers reviewing the AT27C010L-15PI datasheet, AT27C010L-15PI pinout, AT27C010L-15PI application, or AT27C010L-15PI equivalent, key selection criteria include its 32-pin PDIP package, VPP-programming voltage requirement (12.0 V ±0.5 V), integrated product identification code, and low-power active current (25 mA at 5 MHz) versus standard AT27C010 variants.
Technical Context
The AT27C010L-15PI implements a parallel-addressed OTP EPROM architecture with dual-line control (CE and OE) for bus contention management and supports rapid byte-level programming via PGM strobe with VPP = 12.0 V. Its internal logic ensures TTL/CMOS compatibility on all inputs and outputs without external level-shifting.
It uses high-reliability CMOS process technology with 2000 V ESD protection and 200 mA latchup immunity, and integrates a product identification mechanism where A9 = VH and A0 toggles to select manufacturer (0x1E) or device code (0x05) bytes - used by programmers for algorithm auto-selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 128K × 8-bit (1,048,576 bits) - sufficient for boot code or firmware storage in 8-bit microcontroller systems |
| Read Access Time | 150 ns (tACC max) - compatible with 6–7 MHz Z80/8085/68000 bus timing without WAIT states |
| VCC Supply | 5 V ±10% - single-supply operation eliminates need for auxiliary rails in legacy designs |
| Active Current | 25 mA max at 5 MHz - enables low-power system-level power budgeting vs. standard AT27C010 (35 mA) |
| Standby Current | 100 µA max - supports low-quiescent-power sleep modes in industrial controllers |
| Programming Voltage | VPP = 12.0 V ±0.5 V - requires dedicated programming supply; not 5 V-only programmable |

FAQ
What is the maximum operating temperature range for the AT27C010L-15PI?
The AT27C010L-15PI is rated for industrial temperature operation from −40°C to +85°C. This specification is confirmed in the "AT27C010L Ordering Information" table on page 11 of the datasheet, where the "-15PI" suffix explicitly denotes the industrial-grade PDIP variant. It is not qualified for automotive (−40°C to +125°C) or extended commercial ranges.
Does the AT27C010L-15PI require a separate programming voltage during normal read operation?
No. The AT27C010L-15PI operates from a single 5 V ±10% supply (VCC) during read mode. VPP = 12.0 V ±0.5 V is required only during programming - and must be applied after VCC and removed before VCC per datasheet Note 1 on page 7. In read mode, VPP may be tied to VCC or left floating depending on system design, but no external 12 V rail is needed for standard operation.
Can the AT27C010L-15PI be used as a direct replacement for the AT27C010-15PI in an existing PCB layout?
Yes - the AT27C010L-15PI shares identical pinout, package (32P6 PDIP), AC/DC timing specifications (including 150 ns tACC max), and programming interface with the AT27C010-15PI. The only functional difference is lower active current (25 mA vs. 35 mA at 5 MHz), which does not affect signal integrity or timing margins. No PCB changes are required.
How is the product identification code accessed on the AT27C010L-15PI?
The AT27C010L-15PI provides two identification bytes: Manufacturer ID (0x1E) and Device ID (0x05). To read them, hold A1–A16 low, apply VH = 12.0 V ±0.5 V to A9, and toggle A0 between VIL (to read manufacturer byte) and VIH (to read device byte), with CE and OE both low. This is defined in the "Product Identification" section on page 4 and verified in the "Integrated Product Identification Code" table on page 8.
What decoupling capacitance is required for stable operation of the AT27C010L-15PI?
The AT27C010L-15PI requires a 0.1 µF high-frequency ceramic capacitor placed between VCC and GND, mounted as close as possible to the device pins. For systems with multiple EPROMs, a 4.7 µF bulk electrolytic capacitor should also be added near the power entry point. These values are specified in the "System Considerations" section on page 2 to suppress transient excursions during CE switching.
