Product details
Overview
ATF22V10BQ-15PC from Atmel is a high-performance, electrically erasable CMOS programmable logic device (PLD) with 22 inputs, 10 macrocells, and 10 I/O pins. It delivers 15 ns propagation delay (tPD), 8 ns clock-to-output (tCO), and operates at 5V ±5% over 0°C to 70°C. Used in legacy digital control, glue logic, and state machine implementation for industrial instrumentation.
For engineers reviewing the ATF22V10BQ-15PC datasheet, ATF22V10BQ-15PC pinout, ATF22V10BQ-15PC application, or ATF22V10BQ-15PC equivalent, key selection criteria include its 15 ns speed grade, DIP-24 package with standard PLD pinout, Flash-based reprogrammability, and PCI compliance for embedded bus interface logic.
Technical Context
The ATF22V10BQ-15PC implements a fixed-architecture PAL-style logic array with 10 registered outputs, configurable product-term sharing, and asynchronous reset/synchronous preset per macrocell. Its architecture supports both combinatorial and registered logic modes with internal feedback paths.
It uses Atmel's Flash memory technology for nonvolatile configuration storage, enabling full in-system reprogrammability without UV erasure. Input and I/O pull-up resistors ensure defined logic states during power-up or floating conditions, simplifying board-level design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMD AM22V10CPC | Same 22V10 architecture, 15 ns speed grade, but uses EPROM (UV-erasable) instead of Flash | Requires UV eraser and socket programming; unsuitable for field updates or prototyping iterations | Select only when long-term configuration stability is prioritized over reprogrammability |
| Lattice GAL22V10D-15LPC | E2CMOS technology, 15 ns speed, same pinout, but lacks internal pull-ups and PCI compliance | Needs external pull-ups for floating inputs; requires additional validation for PCI bus timing margins | Prefer when cost sensitivity outweighs design simplicity and certification requirements |
Compared with AMD AM22V10CPC and Lattice GAL22V10D-15LPC, the ATF22V10BQ-15PC uniquely combines Flash reprogrammability, built-in pull-ups, and PCI compliance in a drop-in DIP-24 package-reducing qualification effort and enabling post-deployment logic updates without hardware changes.

FAQ
What is the maximum operating frequency supported by the ATF22V10BQ-15PC?
The ATF22V10BQ-15PC supports up to 55.5 MHz in external feedback mode (1/(tS + tCO)), 69 MHz in internal feedback mode, and 83.3 MHz in no-feedback configurations. These values derive directly from its 15 ns tPD, 10 ns tS, and 8 ns tCO specifications under commercial conditions. The ATF22V10BQ-15PC achieves this performance while maintaining full 5V ±5% supply tolerance and 0°C to 70°C ambient operation.
Does the ATF22V10BQ-15PC require external pull-up resistors on its inputs?
No, the ATF22V10BQ-15PC includes internal weak pull-up resistors on all input and I/O pins, ensuring defined logic-high states when left un-driven. This eliminates the need for external pull-ups in most applications, reducing BOM cost and PCB space. The ATF22V10BQ-15PC pull-ups are TTL-compatible and can be overdriven by standard logic drivers without damage or timing penalty.
Is the ATF22V10BQ-15PC pin-compatible with other 22V10 PLDs?
Yes, the ATF22V10BQ-15PC uses the industry-standard 24-pin DIP pinout for 22V10 devices, matching AMD AM22V10, Lattice GAL22V10, and National Semiconductor MM22V10. Pin functions-including CLK/IN (pin 1), GND (pin 12), VCC (pin 24), and I/O (pins 14–22)-are identical. The ATF22V10BQ-15PC maintains full mechanical and electrical compatibility with legacy sockets and PCB footprints.
What programming hardware is required for the ATF22V10BQ-15PC?
The ATF22V10BQ-15PC is programmed using standard CMOS PLD programmers supporting JEDEC file format, such as Data I/O PS-200, BP Microsystems Model 3000, or Xeltek SuperPRO series. No special voltage or timing sequences are needed beyond standard 5V VCC and 12V VPP (if used for security fuse). The ATF22V10BQ-15PC accepts JEDEC files generated by Atmel WinCUPL or third-party PLD compilers.
How does the power-up reset feature function in the ATF22V10BQ-15PC?
The ATF22V10BQ-15PC incorporates an internal power-up reset circuit that asserts a reset pulse when VCC crosses 3.8–4.5 V, forcing all registers to low state. This ensures deterministic initialization of state machines without external reset circuitry. The ATF22V10BQ-15PC requires monotonic VCC ramp-up and adherence to input setup times before first clock edge to guarantee reliable reset behavior.
