Product details
Overview
AT27C010-15PC from Atmel is a 128K × 8-bit one-time programmable EPROM (OTP EPROM) with 45 ns read access time, 5V ±10% supply operation, and JEDEC-standard 32-lead PDIP package. It delivers high-speed firmware storage for microprocessor systems without wait states and supports commercial temperature range (0°C to 70°C).
For engineers reviewing the AT27C010-15PC datasheet, AT27C010-15PC pinout, AT27C010-15PC application, or AT27C010-15PC equivalent, key selection criteria include verified 45 ns tACC, 35 mA active current at 5 MHz, VPP = 12.0 V programming voltage, CMOS/TTL compatibility, and integrated product identification code for automated programming equipment.
Technical Context
The AT27C010-15PC implements a parallel-addressed OTP EPROM architecture with dual-line control (CE and OE) enabling bus contention prevention in multi-device systems. Its Rapid™ Programming Algorithm uses 100 µs/byte pulses with verify-reprogram loops, requiring VPP = 12.0 ± 0.5 V and VCC = 6.5 V during programming.
It features two-stage output enable logic: OE low enables data output only when CE is also low; CE high forces high-impedance outputs regardless of OE state. The device includes dedicated PGM strobe and A9-based product identification mode (VID = 12.0 V), supporting manufacturer and device code reads via A0 toggle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 128K × 8-bit (1,048,576 bits), organized as byte-addressable nonvolatile storage |
| Read Access Time | 45 ns max (tACC), enabling direct interface with 22 MHz microprocessors without wait states |
| VCC Supply | 5V ±10%, compatible with standard TTL/CMOS logic rails and eliminating need for auxiliary supplies |
| Active Current | 35 mA max at 5 MHz, defining power budget for embedded system memory subsystems |
| Standby Current | 100 µA max (ISB1), supporting low-power hold modes in battery-backed or intermittent-operation designs |
| Programming Voltage | VPP = 12.0 ± 0.5 V, requiring dedicated programming supply separate from VCC during write cycles |
| ESD Protection | 2000V HBM, ensuring robustness during handling and board assembly in industrial environments |
Pinout & Package
AT27C010-15PC is supplied in a 32-lead, 0.600" wide plastic dual inline package (PDIP), per JEDEC MS-011 specification. Pin 1 is marked by a notch or dot; package height is 4.95 mm max, width 19.8 mm, length 41.7 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus accepting 0–131071 decimal (128K) locations; CMOS/TTL compatible thresholds |
| O0–O7 | Data Outputs | 8-bit bidirectional data bus (output-only in read mode); VOH ≥ 2.4 V @ –400 µA, VOL ≤ 0.4 V @ 2.1 mA |
| CE | Chip Enable | Active-low global enable; must be low for read or program operations; controls standby current path |
| OE | Output Enable | Active-low output gate; allows data bus sharing without external tri-state logic when CE is asserted |
| PGM | Program Strobe | Active-low pulse input initiating byte programming; requires 95–105 µs width synchronized with VPP |
| VPP | Programming Voltage | 12.0 V input pin; must be applied after VCC and removed before VCC to prevent latchup or damage |
| VCC | Power Supply | +5V supply pin; powers core logic and I/O buffers; requires 0.1 µF ceramic decoupling adjacent to pin |
| GND | Ground Reference | Signal and power return; forms reference for all input thresholds and output drive levels |
| NC | No Connect | Unbonded pin (PDIP pin 18); must remain unconnected to avoid parasitic coupling or ESD paths |
Key Features
| Feature | Design Value |
|---|---|
| Rapid™ Programming Algorithm | 100 µs/byte typical programming time with auto-verify loop, reducing firmware update cycle time in production programming |
| Integrated Product Identification Code | Manufacturer ID (0x1E) and Device Code (0x05) readable via A9=12.0 V and A0 toggle, enabling automatic algorithm selection in universal programmers |
| Two-Line Control Architecture | Independent CE and OE inputs allow flexible bus arbitration-OE can be delayed up to tACC − tOE without affecting access timing |
| High-Reliability Process | 200 mA latchup immunity and 2000 V HBM ESD rating ensure survival in harsh industrial PCB assembly and field environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM27C010-15DC | Same 128K×8 organization and 45 ns speed grade, but uses AMD's process with 50 mA active current and no integrated ID code | Lacks A9-based identification mode; requires manual algorithm selection in programmers | Preferred where legacy AMD toolchains exist and ID code automation is unnecessary |
| MX27C1000PC-15 | 128K×8 OTP EPROM with identical PDIP-32 footprint and 45 ns tACC, but specifies 12.5 V VPP and 40 mA ICC | Higher VPP tolerance (12.5 V vs. 12.0 V) eases margining in aging programmer supplies | Selected when higher VPP headroom is required for long-term programming repeatability |
Compared with AM27C010-15DC and MX27C1000PC-15, the AT27C010-15PC offers lower active current (35 mA), integrated product ID for automated programming, and tighter VPP regulation (±0.5 V), making it optimal for high-volume, algorithm-driven firmware programming workflows.

FAQ
What is the maximum operating temperature range for the AT27C010-15PC?
The AT27C010-15PC is rated for commercial temperature operation from 0°C to +70°C. This range is confirmed in the Ordering Information table on page 10 of the datasheet, where "AT27C010-15PC" is explicitly listed under the Commercial (0°C to 70°C) column. It does not support industrial (–40°C to +85°C) or automotive (–40°C to +125°C) ranges - those require suffixes "I" or "A", respectively.
Does the AT27C010-15PC require a programming voltage higher than VCC during normal read operation?
No. During normal read operation, the AT27C010-15PC requires only a single 5V ±10% supply on VCC; VPP may be tied to VCC or left unconnected. VPP = 12.0 V is required exclusively during programming mode, as specified in the DC Programming Characteristics table (page 6) and Operating Modes table (page 3). Applying 12 V to VPP during read risks damaging the device.
Can the AT27C010-15PC be used as a direct replacement for the AT27C010-15JC or AT27C010-15TC?
Yes - the AT27C010-15PC shares identical electrical specifications, timing (45 ns tACC), and functional behavior with the AT27C010-15JC (PLCC) and AT27C010-15TC (TSOP), differing only in package type (PDIP vs. PLCC vs. TSOP). All three use the same die, same speed grade, and same commercial temperature rating. Pinouts differ across packages, so PCB layout must match the 32P6 PDIP footprint.
What is the purpose of the NC pin on the AT27C010-15PC PDIP package?
The NC (No Connect) pin on the AT27C010-15PC PDIP package (pin 18, per PDIP Top View diagram on page 2) is an unconnected, unbonded terminal. It must remain electrically floating - no trace, pull-up, or capacitor should be attached. Its presence maintains mechanical symmetry and JEDEC-compliant leadframe geometry but carries no internal circuit connection, as confirmed in the Pin Configurations section and Block Diagram (pages 2–3).
How does the Integrated Product Identification Code function in the AT27C010-15PC?
The AT27C010-15PC implements an electronic ID code accessible by asserting VPP = 12.0 V, holding A9 = VH (12.0 V), grounding A1–A16, and toggling A0 between low and high. When A0 = low, O7–O0 output the Manufacturer ID (0x1E); when A0 = high, they output the Device Code (0x05). This feature is used by intelligent programmers to auto-select correct algorithms and verify part authenticity before programming.
