Product details
Overview
ATF1508ASV-15QI160 from Microchip (formerly Atmel) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 128 macrocells, 15 ns maximum pin-to-pin delay, and operation across 3.0V–3.6V supply. It supports registered logic up to 77 MHz, features three global clock inputs, JTAG boundary-scan per IEEE 1149.1, and is packaged in a 160-lead PQFP for industrial temperature range (−40°C to +85°C). It serves as a drop-in replacement for TTL/MSI logic and legacy PLDs in control-plane logic, state machines, and glue logic.
For engineers reviewing the ATF1508ASV-15QI160 datasheet, ATF1508ASV-15QI160 pinout, ATF1508ASV-15QI160 application, or ATF1508ASV-15QI160 equivalent, key selection criteria include its 128-macrocell architecture, programmable slew rate and open-collector outputs, dual power-down pins (PD1/PD2), VCCIO/VCCINT separation, and in-system programmability via standard JTAG interface - all validated for industrial-grade reliability and PCI compliance.
Technical Context
The ATF1508ASV-15QI160 implements a hierarchical CPLD architecture with eight logic chains, each supporting up to 40-product-term sum-of-products logic via cascade paths. Its global bus carries 100+ signals (including all I/Os and buried macrocell feedback), while each logic block selects up to 40 signals via software-configurable switch matrices.
Each of its 128 macrocells integrates five product terms (expandable to 40 via cascade), configurable D/T/latch flip-flops, individual output enable control, programmable pin-keeper, and ITD (Input Transition Detection) on global clocks and I/Os. The device supports both combinatorial and registered outputs with buried feedback independent of output mode.
Key Specifications

Pinout & Package
ATF1508ASV-15QI160 is housed in a 160-lead Plastic Quad Flat Package (PQFP) with exposed pad, rated for industrial temperature (−40°C to +85°C). Pin 1 is located at top-left corner; pin numbering proceeds counterclockwise. Package includes 8 GND and 8 VCC pins distributed for low-inductance power delivery and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK1, GCLK2, GCLK3 | Global Clock Inputs | Three dedicated low-skew clock inputs; each can drive all macrocells or be used as general-purpose inputs when not assigned as clocks. |
| GCLR | Global Asynchronous Clear | Active-low reset controlling all macrocell registers; may be OR'd with product-term reset for selective clearing. |
| OE1, OE2 | Global Output Enable | Two independent output-enable controls; each can be inverted or sourced from I/O pins or product terms. |
| PD1, PD2 | Power-down Control | Active-high pins enabling sub-5 mA power-down mode; latches internal state and holds outputs during sleep. |
| TCK, TMS, TDI, TDO | JTAG Test Access Port | IEEE 1149.1-compliant boundary-scan and ISP interface; TMS/TDI have optional internal pull-ups. |
| VCCIO / VCCINT | Separate Power Rails | VCCIO powers I/O buffers (3.0–3.6V); VCCINT powers core logic - enables mixed-voltage I/O and lower core power. |
| I/Oxx | Bidirectional I/O | Configurable as input, output, or tristate; supports programmable slew rate, open-collector, and pin-keeper functions. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Slew Rate | Per-output control to reduce EMI and crosstalk on high-speed buses without sacrificing timing margin on critical paths. |
| Buried Registered Feedback | Enables dual-latch behavior within a single macrocell - supports compact state machine encoding and pipeline stages. |
| Input Transition Detection (ITD) | Detects edges on global clocks, inputs, and I/Os without consuming macrocell resources - ideal for wake-on-event or glitch-free interrupt generation. |
| Pin-keeper Circuitry | Eliminates need for external pull-ups on unused inputs/I/Os - reduces BOM cost, board space, and DC leakage current. |
| VCC Power-up Reset | Hysteresis-selectable (Small/Large) reset ensures deterministic initialization of all registers at power-on - critical for FSM reliability. |
| Security Fuse & User Signature | One-time programmable fuse blocks readback; two user-accessible bytes store revision, project ID, or calibration data - traceable across firmware versions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1508ASVL-15QI160 | Same die, "L" suffix denotes automatic 5 µA standby mode; identical pinout and AC specs. | Preferred where lowest quiescent current is mandatory (e.g., battery-backed systems); no change to PCB or firmware. | Select ATF1508ASVL-15QI160 only if automatic low-power mode is required - otherwise ATF1508ASV-15QI160 offers full pin control over standby entry. |
| XCR3256XL-10TQ144I | Xilinx CoolRunner-II CPLD: 256 macrocells, 10 ns speed grade, 144-pin TQFP; higher density but different toolchain and power profile. | Suitable for designs needing >128 macrocells or faster timing; requires Xilinx WebPACK and separate JTAG programmer (no native ISP via same cable). | Choose XCR3256XL-10TQ144I only when scaling beyond 128 macrocells - ATF1508ASV-15QI160 remains optimal for cost-sensitive, pin-locked industrial upgrades. |
Compared with ATF1508ASVL-15QI160, the ATF1508ASV-15QI160 gives designers explicit control over standby activation via PD1/PD2 pins rather than relying on automatic detection - enabling synchronized power gating across multiple devices. Against XCR3256XL-10TQ144I, it trades macrocell count for seamless Atmel toolchain integration, lower system-level BOM cost, and guaranteed in-field reprogrammability without changing hardware.

FAQ
What is the maximum operating frequency of the ATF1508ASV-15QI160?
The ATF1508ASV-15QI160 supports registered operation up to 77 MHz, with a maximum internal global clock frequency of 76.9 MHz (tCNT = 13 ns minimum period). Its 15 ns pin-to-pin delay enables reliable timing closure in synchronous designs running at ≤77 MHz, provided setup/hold times are met and slew rate settings are optimized for signal integrity.
Does the ATF1508ASV-15QI160 require an external configuration PROM?
No, the ATF1508ASV-15QI160 does not require an external configuration PROM. It uses on-chip electrically-erasable (EE) technology and retains its logic configuration indefinitely (20-year data retention) without external memory. Configuration is loaded at power-up from internal nonvolatile cells - eliminating boot-time delays and external component dependencies.
Can the JTAG pins of the ATF1508ASV-15QI160 be used as general-purpose I/Os?
Yes, the JTAG pins (TCK, TMS, TDI, TDO) of the ATF1508ASV-15QI160 can be repurposed as general-purpose I/Os if JTAG boundary-scan testing and in-system programming are disabled in the design file. When disabled, these four pins become fully functional I/Os - increasing the usable I/O count from 96 to 100 while retaining all macrocell logic resources.
What is the purpose of the PD1 and PD2 pins on the ATF1508ASV-15QI160?
The PD1 and PD2 pins on the ATF1508ASV-15QI160 provide pin-controlled power-down functionality. When either pin is driven high (with power-down mode enabled in the design), the device enters a sub-5 mA low-power state while latching all internal logic states and maintaining valid output levels. This feature enables precise system-level power gating without requiring firmware intervention or external supervisors.
How does the ATF1508ASV-15QI160 handle power-up initialization?
The ATF1508ASV-15QI160 incorporates a VCC-sensing power-up reset circuit that initializes all registers when VCC crosses the VRST threshold. Users may select Small or Large hysteresis; Atmel recommends Large hysteresis for 3.0V operation to ensure robust reset behavior. With Large hysteresis enabled, ICC drops by several hundred microamps, improving efficiency in low-voltage industrial systems.
