Product details
Overview
AT27C010-15JC from Atmel is a 1-Mbit (128K × 8) one-time programmable EPROM with 150 ns maximum access time, 5V ±10% supply operation, and JEDEC-standard 32-lead PLCC packaging. It delivers CMOS/TTL-compatible I/O, rapid 100 µs/byte programming, and supports commercial temperature range (0°C to 70°C) for firmware storage in microprocessor-based systems.
For engineers reviewing the AT27C010-15JC datasheet, AT27C010-15JC pinout, AT27C010-15JC application, or AT27C010-15JC equivalent, key selection criteria include verified read timing (tACC = 150 ns), standby current ≤100 µA, VPP = 12.0 V programming voltage, and PLCC package compatibility with legacy socketed EPROM designs.
Technical Context
The AT27C010-15JC implements a standard OTP EPROM architecture with dual-line control (CE and OE) enabling bus contention prevention in shared-memory systems. Its address space spans A0–A16 (128K locations), with O0–O7 bidirectional data outputs and dedicated PGM strobe for programming.
It operates in five distinct modes-Read, Output Disable, Standby, Rapid Program, and Product Identification-each defined by specific CE/OE/PGM logic states and VPP voltage conditions. The Integrated Product Identification Code uses A9 high-voltage (12.0 V) and A0 toggling to return manufacturer (0x1E) and device (0x05) codes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar OTP EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT27C010-15PC | Same die, 32-lead PDIP package (0.600" width) instead of PLCC; identical timing, current, and programming specs | Designed for through-hole PCB assembly and socketed prototyping; lacks surface-mount footprint | Select when using legacy DIP sockets or wave-solder manufacturing flow |
| AT27C010-15TC | Same die, 32-lead TSOP package (JEDEC MO-142 BD); same electrical specs but thinner profile (1.2 mm max height) | Optimized for space-constrained boards; requires reflow soldering and tighter layout clearance | Select when board real estate is limited and SMT assembly is available |

FAQ
What is the maximum access time specified for the AT27C010-15JC?
The AT27C010-15JC has a maximum address-to-output delay (tACC) of 150 ns under standard read conditions (CE = OE = VIL, VCC = 5V ±10%, TA = 25°C). This value is guaranteed across the commercial temperature range (0°C to 70°C) and defines the longest time required to retrieve valid data after address stabilization. The AT27C010-15JC meets this spec without requiring WAIT states on microprocessors operating up to ~6.7 MHz.
Does the AT27C010-15JC require a separate programming voltage during normal operation?
No - the AT27C010-15JC operates solely from a 5V ±10% VCC supply during read mode. The 12.0 V VPP voltage is required only during programming and must be applied after VCC and removed before VCC to prevent damage. In standby and active read modes, VPP may be tied to VCC, but doing so increases total supply current; the AT27C010-15JC datasheet specifies VPP = VCC for standby current measurement (IPP1).
How is the Integrated Product Identification Code accessed on the AT27C010-15JC?
The AT27C010-15JC returns its Manufacturer ID (0x1E) and Device ID (0x05) via the O0–O7 pins when A9 is driven to 12.0 V (VID = 11.5–12.5 V) and A0 is toggled: A0 = VIL selects the Manufacturer byte, A0 = VIH selects the Device byte. All other address lines (A1–A16) must be held low (VIL). This feature is used by industry-standard programmers to auto-detect the device and apply correct algorithms - no special command sequences are needed.
Can the AT27C010-15JC be used in place of the AT27C010L-15JC?
No - the AT27C010-15JC and AT27C010L-15JC are distinct parts with different active current ratings: the AT27C010-15JC draws up to 35 mA in active read mode, while the AT27C010L-15JC draws only 25 mA. They share identical timing (150 ns), package, and pinout, but substituting one for the other requires verifying that the target system's power delivery and thermal design accommodate the higher ICC of the AT27C010-15JC.
What decoupling capacitors are required for stable operation of the AT27C010-15JC?
The AT27C010-15JC requires two decoupling capacitors: a 0.1 µF high-frequency ceramic capacitor placed between VCC and GND as close to the device pins as possible, and a 4.7 µF bulk electrolytic capacitor located near the power supply entry point for arrays of multiple EPROMs. These values are mandated in the "System Considerations" section to suppress transient voltage excursions during CE switching and ensure reliable operation within datasheet voltage limits.
