ATF22V10C-15JC - 15ns Flash EPLD, 10 Macrocell | Microchip
MPN： ATF22V10C-15JC ✓ 啟用中ATF22V10C-15JC 概覽
An electrically erasable programmable logic device, or EEPLD, belongs to the programmable-logic-device hierarchy alongside SPLD, CPLD, and FPGA devices. Unlike mask-programmed or fuse-programmed alternatives, the ATF22V10C uses Flash memory to store its configuration electronically. This allows a finished board to be reprogrammed in place, which simplifies production revisions, prototype updates, and field maintenance.
Key features of the ATF22V10C family include programmable macrocells, speeds down to 5 ns across the broader family, and low power dissipation with typical standby current reported as low as 10 µA. The -15JC ordering code identifies the 15 ns speed grade and commercial temperature option. Microchip identifies the device as an EEPLD with 10 macrocells, 500 gates, and a 28-PLCC package.
The ATF22V10C architecture implements logic through a JEDEC-compatible fuse map. Microchip states that the ATF22V10C family is pin-to-pin and JEDEC fuse-map compatible with the GAL22V10, making it a practical migration path for boards designed around that established programmable-logic footprint. The JEDEC-compatible architecture allows the same device-programming conventions and board-level pin assignments to be retained.
Typical uses include bus decoding, address translation, control-signal generation, data-routing functions, and legacy glue-logic replacement. Its 15 ns speed grade is appropriate for general-purpose control logic where the device must operate close to slower TTL or CMOS system buses. The ATF22V10C is especially relevant to maintenance of older industrial, communications, instrumentation, and embedded-control equipment that previously relied on GAL22V10 or comparable 22V10 devices.
Designers should verify the exact pin assignment, operating voltage limits, temperature limits, and programming-device requirements in the manufacturer datasheet before substituting it into an existing board. Flash configuration updates require the appropriate programming algorithm and electrical connection sequence. Confirm the -15 speed grade and JC package or temperature suffix against the original BOM rather than relying only on the 22V10 family name.
This page consolidates the verified device specifications, manufacturer documentation, programming and pinout references, and practical migration guidance for engineers evaluating the ATF22V10C-15JC as a flash-based 22V10 replacement.

典型應用
ATF22V10C-15JC 適用於 6 應用s: Legacy GAL22V10 Board Migration, Industrial Control and Address Decoding, Bus Interface and Data Routing, Embedded Control Signal Generation, Instrumentation and Measurement Control, Telecommunications Status and Routing Logic.
Legacy GAL22V10 Board Migration
The ATF22V10C-15JC fits maintenance and redesign programs for boards built around the GAL22V10 because the ATF22V10C family is identified as pin-to-pin and JEDEC fuse-map compatible. Its 10 macrocells and 500-gate capacity preserve the familiar 22V10 implementation model, while the 15 ns grade targets general control logic rather than demanding synchronous datapaths. The principal engineering benefit is Flash-based electrical reconfiguration, allowing configuration changes without relying on irreversible fuse programming.
推薦
Industrial Control and Address Decoding
The ATF22V10C-15JC is appropriate for industrial control boards that decode addresses, qualify switch positions, or generate sequencing signals. Its 10 macrocells can implement multiple registered and combinational functions, and the latch feature holds inputs at their previous logic states for synchronization. The 15 ns speed rating supports general-purpose control logic, but engineers should compare the device timing against the slowest associated bus and account for the commercial temperature grade specified by the -JC suffix.
推薦
Bus Interface and Data Routing
Use the ATF22V10C-15JC for modest bus-decoding and data-routing functions where 500 gates and 10 macrocells are sufficient. Its JEDEC-compatible 22V10 architecture simplifies migration from GAL22V10-based assemblies, and the 5 V supply matches legacy TTL and CMOS control boards. Unlike an FPGA, the device has a fixed macrocell structure, so designs must be checked against the available product terms and I/O allocation rather than assuming arbitrary logic depth.
推薦
Embedded Control Signal Generation
The ATF22V10C-15JC can generate enable, reset, interlock, and sequencing signals in embedded-control equipment. Ten macrocells provide enough capacity for several related state-machine or decode functions while keeping the implementation in a compact 28-PLCC package. Its 15 ns grade and latch feature assist in synchronizing combinational decisions, while typical standby current as low as 10 µA is useful in low-duty-cycle control systems where the supply remains present but logic activity is intermittent.
推薦
Instrumentation and Measurement Control
The ATF22V10C-15JC is suitable for instrumentation front ends that need range decoding, mode selection, or command validation. Its fixed 22V10 structure is well matched to deterministic glue logic, and its 5 V operation aligns with many legacy measurement boards. The device does not replace a precision converter or analog front end; instead, it complements them by controlling selection paths and isolating digital sequencing decisions. Validate input levels, setup time, and unused-pin handling in the manufacturer data sheet.
推薦
Telecommunications Status and Routing Logic
The ATF22V10C-15JC can implement status decoding, path selection, and supervisory control functions in telecommunications equipment built around legacy 22V10 devices. The 15 ns speed grade is appropriate for slow supervisory and backplane-control paths, while the 28-PLCC package supports a familiar assembly footprint. Flash programmability simplifies field maintenance and engineering-change orders, although designers must confirm supply-voltage tolerance, temperature limits, and the exact JEDEC fuse map for each board revision.

主要差異化特點
- Electrically erasable Flash configuration (對比GAL22V10D)
- Direct 22V10 migration architecture (對比ATF22V10C-5JX)

設計說明
Do not substitute only by the 22V10 family designation. The -15 part of ATF22V10C-15JC specifies a 15 ns speed grade, while JC identifies the commercial ordering option. Confirm the original GAL22V10 or ATF22V10C speed, temperature range, supply tolerance, package dimensions, and fuse map. Microchip identifies the ATF22V10C family as pin-to-pin and JEDEC fuse-map compatible with the GAL22V10, but qualification and environmental suffixes still require verification.
Preserve the land pattern and pin numbering of the original 28-PLCC assembly when migrating a legacy board. J-bend leads require a footprint designed for PLCC mounting rather than a generic QFN or gull-wing arrangement. Check pin-1 orientation, lead pitch, body clearance, and solder-joint access against the manufacturer package drawing. Because the available package-diagram library lacks PLCC-28, the manufacturer drawing should control the mechanical implementation.
The ATF22V10C-15JC operates from a nominal 5 V supply. Commercial-grade speed ranges are specified over 5 V ± 5%, while military and industrial ranges use 5 V ± 10%. Apply the grade-specific limit from the data sheet rather than treating all suffixes as electrically identical. Provide local supply decoupling close to the device and route programming and signal pins away from noisy switching nodes to reduce false transitions in registered control logic.
Validate every system interface against the 15 ns device timing rather than only the nominal bus clock. Include macrocell propagation delay, setup and hold requirements, and any latch behavior in the worst-case path analysis. Leave unused inputs in a defined state and follow the datasheet's termination recommendations. For legacy backplanes, account for ringing and skew rather than assuming that a nominal 15 ns part closes timing margin automatically.
