Product details
Overview
AT27C010L-45TI 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, rapid programming at 100 µs/byte, and dual-line control (CE/OE) for bus contention prevention in microprocessor systems.
For engineers reviewing the AT27C010L-45TI datasheet, AT27C010L-45TI pinout, AT27C010L-45TI application, or AT27C010L-45TI equivalent, key selection criteria include low active current (25 mA @ 5 MHz), 100 µA max standby, JEDEC-standard 32-lead TSOP package, and integrated product identification code for automated programming equipment compatibility.
Technical Context
The AT27C010L-45TI implements a parallel-addressed OTP EPROM architecture with 17 address lines (A0–A16), 8 bidirectional data outputs (O0–O7), and dedicated control pins (CE, OE, PGM) enabling precise read, standby, and rapid programming modes. Its Rapid™ algorithm uses 100 µs PGM pulses with verification loops per byte, requiring VPP = 13.0 V during programming and VCC = 6.5 V.
It supports three operating modes: Read (CE=OE=VIL), Standby (CE=VIH), and Rapid Program (CE=VIL, OE=VIH, PGM=VIL). The device integrates product identification via A9 high-voltage sensing (12.0 V ±0.5 V) and A0 toggling to select manufacturer/device code bytes, ensuring compatibility with industry-standard programmers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-45TI | Higher active current (35 mA vs. 25 mA); same 45 ns access, 5V supply, and TSOP package | Suitable for systems with higher thermal budget but identical timing and footprint requirements | Select when lower standby current is not critical and existing design uses standard AT27C010 firmware images |
| MX27C1000PC-45 | Same 128K×8 OTP EPROM, 45 ns access, 5V supply; requires VPP = 12.5 V (not 13.0 V) and lacks integrated ID code | Compatible in read-mode interfaces but requires programmer firmware modification for programming voltage and ID detection | Choose for cost-sensitive industrial designs where universal programmer support is not required |
Compared with AT27C010-45TI and MX27C1000PC-45, the AT27C010L-45TI delivers lower active power and built-in identification-critical for automated programming lines-while maintaining pin-for-pin compatibility in TSOP packages and identical AC timing.

FAQ
What is the maximum programming voltage required for AT27C010L-45TI?
The AT27C010L-45TI requires VPP = 13.0 V ± 0.25 V during programming, applied only to pin 16 (VPP) while VCC is held at 6.5 V ± 0.25 V. This voltage must be applied after VCC and removed before VCC to prevent latchup. The AT27C010L-45TI datasheet specifies VID on A9 at 12.0 V ± 0.5 V for product identification, distinct from VPP.
Does AT27C010L-45TI support in-system programming?
No, the AT27C010L-45TI does not support in-system programming. It requires a dedicated EPROM programmer applying 13.0 V to VPP and using the Rapid™ algorithm with 100 µs PGM pulses. The device lacks serial interface or internal charge pumps needed for ISP, and its TSOP package is not socketed for field reprogramming.
What is the meaning of the 'L' suffix in AT27C010L-45TI?
The 'L' in AT27C010L-45TI denotes the low-power variant, distinguishing it from the standard AT27C010. Specifically, the AT27C010L-45TI draws 25 mA max active current at 5 MHz versus 35 mA for the AT27C010-45TI, and 100 µA max standby versus 1 mA for TTL-level CE. Both share identical 45 ns access time and pinout.
Can AT27C010L-45TI operate with 3.3V logic interfaces?
No, the AT27C010L-45TI is strictly a 5V device: VCC must be 5V ±10%, VIH minimum is 2.0 V, and VOH minimum is 2.4 V at –400 µA. Direct connection to 3.3V systems risks undriven outputs and violates DC operating conditions; level-shifting circuitry is required for interoperability.
How is the product identification code accessed on AT27C010L-45TI?
The AT27C010L-45TI product identification code is accessed by setting A9 to 12.0 V ± 0.5 V (VID), holding A1–A16 low, and toggling A0 between VIL and VIH. When A0 = VIL, the Manufacturer ID (0x1E) appears on O7–O0; when A0 = VIH, the Device Code (0x05) is output. This occurs during normal read mode with CE and OE asserted.
