Product details
Overview
ATF22V10B-15SC 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), supports 5 V ±10% supply across industrial and military temperature ranges (–40°C to +85°C / –55°C to +125°C), and features internal pull-up resistors on all inputs and I/Os for robust floating-pin handling in legacy TTL/CMOS systems.
For engineers reviewing the ATF22V10B-15SC datasheet, ATF22V10B-15SC pinout, ATF22V10B-15SC application, or ATF22V10B-15SC equivalent, this device serves as a reprogrammable, Flash-based replacement for 22V10 PALs in glue logic, state machine control, bus interfacing, and PCI-compliant peripheral decoding - with verified timing, latchup immunity, and 20-year data retention.
Technical Context
The ATF22V10B-15SC implements a fixed architecture with 22 input pins feeding a programmable AND-OR logic array and 10 macrocells, each configurable as registered or combinatorial output. Its clocked operation supports synchronous reset, preset, and feedback paths with tCO ≤ 8 ns and tS ≤ 10 ns.
It uses Atmel's Flash memory technology for nonvolatile configuration storage, enabling in-system reprogramming without UV erasure. Internal pull-ups eliminate external biasing needs, while 2,000V ESD protection and 200mA latchup immunity ensure reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 15 ns max - guarantees deterministic timing for 55.5 MHz external-feedback operation in synchronous logic designs |
| Supply Voltage | 5 V ±10% - compatible with legacy 5V TTL/CMOS rails without regulation overhead |
| Operating Temperature | –40°C to +85°C (industrial) or –55°C to +125°C (military) - validated for extended ambient and case conditions |
| Power Supply Current (ICC, standby) | 65–115 mA - low quiescent draw enables use in power-constrained embedded control subsystems |
| Data Retention | 20 years - ensures long-term firmware integrity without battery backup or refresh cycles |
| ESD Protection | 2,000 V HBM - protects against handling damage during manual assembly and field service |
| Latchup Immunity | 200 mA - prevents destructive latchup under transient overvoltage or ground bounce |
Pinout & Package
ATF22V10B-15SC is supplied in a 24-lead, 0.300" wide ceramic dual-in-line package (Cerdip, MIL-STD-1835 D-9 CONFIG A), with standard 22V10 pinout and lead spacing compatible with legacy sockets and wave-solder processes.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1–11, 13, 23–24 | IN | 22 dedicated logic inputs - support TTL/CMOS voltage thresholds and internal weak pull-ups for default-high behavior |
| 12 | GND | Ground reference - decoupling capacitor placement critical for noise suppression in high-speed PLD switching |
| 14–22 | I/O | 10 bidirectional I/O pins - configurable per macrocell as input, combinatorial output, or registered output with OE control |
| 24 | VCC | +5 V supply - requires local 0.1 µF ceramic bypass capacitor to maintain stable core voltage during logic transitions |
| 1 (CLK/IN) | Clock or Input | Shared pin - functions as global clock when used with registered outputs; otherwise operates as general-purpose input |
Key Features
| Feature | Design Value |
|---|---|
| Electrically erasable Flash programming | Enables field firmware updates and design iteration without UV erasers or socket removal |
| Internal input/I/O pull-up resistors | Eliminates need for 10 kΩ external pull-ups - reduces BOM count and PCB real estate in legacy system upgrades |
| PCI compliance | Validated signal integrity and timing margins for plug-in peripheral cards operating at 33 MHz |
| Power-up reset circuitry | Guarantees known register state (low) at VCC ≥ 3.8 V - essential for deterministic state machine boot sequences |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMD AM22V10CPC | UV-erasable EPROM-based; requires UV eraser and socket programming; no internal pull-ups | Not suitable for in-system reprogramming or hot-swap scenarios; higher risk of accidental erase | Select only if legacy toolchain compatibility outweighs field-update capability |
| Lattice GAL22V10D-15LP | E2CMOS technology; 15 ns speed grade; 5 V operation; includes programmable output polarity and slew rate control | Better noise immunity and flexible output drive, but lacks built-in power-up reset and 64-bit signature memory | Prefer for new designs needing enhanced I/O control; ATF22V10B-15SC remains optimal for drop-in 22V10 replacements |
Compared with AMD AM22V10CPC and Lattice GAL22V10D-15LP, the ATF22V10B-15SC uniquely combines Flash reprogrammability, internal pull-ups, power-up reset, and 64-bit user signature in a drop-in 22V10 form factor - making it the most direct upgrade path for legacy systems requiring zero-layout change and guaranteed initialization behavior.

FAQ
What is the maximum operating frequency supported by the ATF22V10B-15SC?
The ATF22V10B-15SC 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 are guaranteed across the full industrial and military temperature ranges with 5 V ±10% supply, making the ATF22V10B-15SC suitable for high-speed glue logic in timing-critical applications.
Does the ATF22V10B-15SC require external pull-up resistors on its inputs?
No - the ATF22V10B-15SC integrates 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 10 kΩ pull-ups in most legacy TTL/CMOS designs, simplifying board layout and reducing BOM cost while maintaining compatibility with standard 22V10 pin behavior.
Is the ATF22V10B-15SC pin-compatible with standard 22V10 devices?
Yes - the ATF22V10B-15SC uses the industry-standard 24-pin DIP pinout (24D3 package) with identical signal assignments to the original MMI 22V10 and subsequent PAL22V10 variants. Its CLK/IN, IN, I/O, GND, and VCC pin positions match exactly, enabling true drop-in replacement in existing sockets and PCB footprints.
How many times can the ATF22V10B-15SC be reprogrammed?
The ATF22V10B-15SC is rated for 100 erase/write cycles under specified operating conditions. Each cycle fully erases the Flash configuration memory and allows complete reprogramming via standard PLD programmers. This endurance supports multiple design iterations and field firmware updates throughout the product lifecycle without degradation.
What is the purpose of the 64-bit user signature memory in the ATF22V10B-15SC?
The 64-bit user signature memory in the ATF22V10B-15SC provides nonvolatile, unsecured storage accessible even when the security fuse is programmed. It is commonly used to store firmware version IDs, manufacturing lot codes, or calibration constants - enabling traceability and diagnostics without consuming logic array resources or requiring external EEPROM.
