ATF22V10B-15PC - 10-Macrocell 15 ns Flash PLD | Microchip
料号： ATF22V10B-15PC ✓ 量产中ATF22V10B-15PC 概述
A programmable logic device is a user-programmable semiconductor that replaces several discrete gates, counters, decoders, and state machines with one configurable integrated circuit. The ATF22V10B belongs to the simple PLD hierarchy, where each of its 10 macrocells implements a sum-of-products logic function through configurable AND and OR structures. This places the device below CPLDs and FPGAs in general complexity while providing nonvolatile, field-reprogrammable logic.
The ATF22V10B family supports programming speeds down to 7.5 ns, although the ATF22V10B-15PC is the 15 ns grade identified by its part-number suffix. Reported power dissipation can be as low as 10 mA. The device is reprogrammable, is described as 100% tested, and includes 2,000 V ESD protection and 200 mA latchup immunity. These characteristics suit control, decoding, address translation, and legacy interface logic that must retain its configuration when power is removed.
The ATF22V10B architecture is organized around 10 PAL-style macrocells. Each macrocell can combine multiple product terms, allowing compact implementations of common combinational and sequential functions. Unlike a mask-programmed PAL device, the electrically erasable Flash configuration permits the same physical device to be reprogrammed during development or field updates. The family also includes military, commercial, and industrial temperature options, with speed ranges characterized across their respective supply conditions.
Typical uses include legacy bus-interface decoding, printer and copier control, industrial automation, embedded control-interface translation, and small state machines. Its 24-pin PDIP format is useful for prototypes, legacy motherboard designs, and equipment where socketed or through-hole assembly is preferred. For new high-density or high-speed designs, an FPGA or CPLD may provide more routing flexibility, but the ATF22V10B-15PC remains useful when its 10-macrocell architecture is sufficient.
Designers should follow the pin-connection and programming guidance in the manufacturer datasheet, preserve adequate supply decoupling, and account for the 15 ns speed grade when evaluating address-decoder or control-path timing. A conventional 24-pin DIP footprint should not be assumed equivalent to every 24-pin PLD without checking pin functions, power rails, programming interface connections, and output behavior.
This page combines device specifications, practical replacement guidance, package-level comparison, and design guidance for engineers evaluating the ATF22V10B-15PC. It also distinguishes directly relevant 24-pin alternatives from related devices whose temperature grade, qualification, speed, or package may prevent a true drop-in substitution.

典型应用
ATF22V10B-15PC 适用于 6 应用s: Legacy Bus Interface Decoding, Industrial State Machine Control, Printer and Copier Control Logic, Interface Signal Conditioning, Instrumentation Control Panel, Data Retention and Timing Store.
Legacy Bus Interface Decoding
The ATF22V10B-15PC is suitable for compact bus decode and address qualification logic because its 10 PAL-style macrocells can implement multiple sum-of-products functions while the 15 ns grade provides a defined propagation-speed class. A designer can use it for chip-select generation, address translation, interrupt routing, or command decoding where the logic remains below approximately 500 gate equivalents. The 24-pin PDIP package also simplifies assembly into older backplane and instrument architectures. Before implementation, verify each pin assignment and timing path against the manufacturer data, since the programmed equations and external bus timing determine whether the device meets the system deadline.
推荐
Industrial State Machine Control
The ATF22V10B-15PC can implement compact sequencing and control functions in industrial equipment because 10 macrocells provide enough capacity for distributed state machines, interlock logic, and output-command decoding. Its 15 ns speed grade is useful for short control paths and registered interfaces, while electrically erasable Flash configuration supports in-circuit design revisions and field updates without replacing the device. The through-hole 24-pin PDIP format assists serviceable legacy control boards. Engineers should still validate reset behavior, output timing, supply tolerance, and temperature grade for the production environment, and should create the design using the manufacturer's programming and pin-description tables.
推荐
Printer and Copier Control Logic
ATF22V10B-15PC applications include printer, copier, and scanner mechanism control where compact combinational logic coordinates sensors, motors, indicators, and interlocks. Its 500-gate-equivalent Flash PLD architecture is appropriate for consolidating repetitive decoder and sequencing functions without using a larger microcontroller. The 15 ns grade helps maintain timing predictability in short control chains, and the 24-pin PDIP package is convenient for replacement boards and legacy test equipment. For a new platform, evaluate whether existing firmware can configure the device and whether every active-high, active-low, clocked, and output signal can be mapped without a PCB change.
推荐
Interface Signal Conditioning
The ATF22V10B-15PC can consolidate protocol-adaptation and signal-conditioning functions such as command remapping, handshake generation, pulse qualification, and data-route selection. Ten macrocells make the device practical for small protocol bridges or fixed-format interfaces, while its reprogrammable configuration permits logic revisions during hardware bring-up. The 15 ns target speed should be compared with the slowest required input-to-output path rather than assumed to satisfy every protocol timing target. A complete design must also confirm that the 24-pin package has the required I/O, supply, clock, and programming connections and that the selected output structure preserves required edge and polarity behavior.
推荐
Instrumentation Control Panel
ATF22V10B-15PC is well suited to instrumentation control panels where switch matrices, indicator drivers, range-selection logic, and status decoding must be coordinated. The compact 500-gate-equivalent architecture can replace multiple discrete logic blocks, while the 24-pin PDIP package is practical for panel boards and prototypes assembled with through-hole techniques. The device's 5 V CMOS operation aligns with many legacy digital instrument architectures, but the designer must verify input thresholds, output drive, supply sequencing, and timing margin. Programming the Flash configuration during calibration can simplify board variants, although the end product must protect unauthorized configuration changes where system integrity matters.
推荐
Data Retention and Timing Store
The ATF22V10B-15PC can retain a programmed truth table, state definition, or control map for systems that require configuration to survive power removal without a microcontroller configuration sequence. Its 20-year data-retention specification and electrically erasable Flash technology distinguish it from volatile programmable logic. Possible uses include storing legacy personality bits, lookup equations, or boot-time interface maps. The 100 erase/write cycle rating should be considered if the configuration changes repeatedly during production or field maintenance. The implementation should also include correct power-up behavior, defined inputs during configuration, and a controlled update process to avoid an invalid intermediate configuration state.

设计说明
Do not treat a matching 24-pin PDIP outline as proof of drop-in compatibility. Compare the complete pin-description tables for power, ground, clock, configuration, and I/O functions, then check propagation delays, output polarity, supply tolerance, and programming requirements. The PALCE22V10H-15PC and PALC22V10D-15PC share the 10-macrocell, 15 ns, 24-PDIP class, but their device architectures still require design-level validation. Revise the schematic, PCB, and configuration file together if any pin function changes.
Create the PCB footprint from the manufacturer's 24-pin PDIP package drawing rather than a generic DIP footprint. Confirm row spacing, pin length, hole diameter, and body width before layout. Place the device where the through-hole package matches the mechanical design, route sensitive clock or control nets away from long switching-current paths, and provide normal supply bypassing close to the device. Inspect assembled boards for solder bridges around adjacent 24-pin leads because small pin spacing can complicate rework.
The ATF22V10B family is a nominal 5 V CMOS device, and its published power dissipation can be as low as 10 mA under the manufacturer's stated conditions. Estimate a production value using the actual implemented logic, switching activity, input levels, output loading, and operating temperature rather than using 10 mA as a universal design value. Verify the selected variant's military or industrial supply range, which is specified over 5 V +/- 10%, and include startup and power-supply margin in the system budget.
Use the 15 ns speed designation as one input to timing analysis rather than as the complete system timing guarantee. Include macrocell propagation delay, external logic delay, setup time, skew, and the required output arrival deadline in the critical path. For clocks, counter outputs, or encoded control signals, check whether the configured equation introduces a combinational glitch and whether an external register or synchronizer is required. A pin-compatible substitute must meet the same timing path, not merely share a package outline.
合规信息
The ATF22V10B is a legacy programmable logic device and is not presented as an automotive-qualified AEC-Q100 product. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from current manufacturer or distributor documentation.
