Microchip Technology ATF22V10BQ-15JC

Overview

ATF22V10BQ-15JC from Atmel is a high-performance, electrically erasable programmable logic device (PLD) based on Flash technology, delivering 15 ns propagation delay, 55.5 MHz maximum operating frequency, and 10 mA standby current at commercial temperature range. It features 10 macrocells, 22 input pins (including CLK/IN), and 10 I/O bidirectional buffers, used in legacy digital control, glue logic replacement, and industrial timing circuits.

For engineers reviewing the ATF22V10BQ-15JC datasheet, ATF22V10BQ-15JC pinout, ATF22V10BQ-15JC application, or ATF22V10BQ-15JC equivalent, key selection criteria include its 15 ns tPD, PCI compliance, internal pull-up resistors on all inputs/I/Os, and support for power-up reset with 600–1000 ns tPR timing.

Technical Context

The ATF22V10BQ-15JC implements a fixed-architecture PLD with 22-input/10-output logic array, configurable as combinational or registered outputs. Its architecture includes synchronous clocking, asynchronous reset, and synchronous preset capability-enabling state machine implementation without external latches.

It uses Atmel's Flash-based nonvolatile memory for configuration storage, supporting full reprogrammability with 100 erase/write cycles and 20-year data retention. All I/Os are CMOS/TTL-compatible with VIL = 0.8 V, VIH = 2.0 V, VOL = 0.5 V at 16 mA, and VOH = 2.4 V at –4 mA.

Manufacturer

Atmel Corporation was a U.S.-based semiconductor company specializing in microcontrollers, nonvolatile memory, and programmable logic devices before its acquisition by Microchip Technology in 2016.

The ATF22V10B series was designed as a Flash-based, reprogrammable alternative to bipolar PALs for cost-sensitive, medium-complexity digital logic applications in commercial and industrial systems.

FAQ

What is the maximum operating frequency of the ATF22V10BQ-15JC?

The ATF22V10BQ-15JC supports a maximum operating frequency of 55.5 MHz under external feedback configuration, as specified in its AC characteristics table. This value derives from the sum of tS (10 ns setup time) and tCO (8 ns clock-to-output delay). The device achieves higher internal feedback rates up to 69 MHz, but system-level timing must account for board-level routing delays and loading effects.

Does the ATF22V10BQ-15JC require external pull-up resistors on its inputs?

No, the ATF22V10BQ-15JC includes internal pull-up resistors on all IN and I/O pins, eliminating the need for external components in most applications. These weak active pull-ups ensure defined logic states when pins are left floating, and they can be easily overridden by standard TTL-compatible drivers - a feature confirmed in Section 14 of the official Atmel datasheet.

Is the ATF22V10BQ-15JC pin-compatible with other ATF22V10 variants?

Yes, the ATF22V10BQ-15JC shares identical pinout and package dimensions with all ATF22V10B and ATF22V10C variants in the 28-pin PLCC (28L) package, including ATF22V10B-15GM/883 and ATF22V10CQZ-15JU. This allows direct substitution within the same socket when speed, temperature, and feature requirements align.

What programming voltage does the ATF22V10BQ-15JC require?

The ATF22V10BQ-15JC uses standard 5 V programming voltage - no elevated VPP is needed. It is programmed using industry-standard PLD programmers that support JEDEC file download, such as Data I/O PS-200 or BP Microsystems Model 3000. Programming occurs at VCC = 5 V ±5%, consistent with its operational supply range.

How does the power-up reset function work in the ATF22V10BQ-15JC?

The ATF22V10BQ-15JC incorporates an internal power-up reset circuit that asserts reset when VCC crosses VRST (3.8–4.5 V), holding registers low for 600–1000 ns (tPR). This ensures deterministic initialization of registered outputs at power-on, provided VCC rise is monotonic and input setup times are met before the first clock edge - a requirement explicitly documented in Section 9 of the Atmel datasheet.
