Product details
Overview
ATF1508ASV-15QC160 from Microchip Technology (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. 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 control logic consolidation.
For engineers reviewing the ATF1508ASV-15QC160 datasheet, ATF1508ASV-15QC160 pinout, ATF1508ASV-15QC160 application, or ATF1508ASV-15QC160 equivalent, this device serves as a reprogrammable, in-system programmable logic replacement for TTL/MSI/LSI functions in legacy interface bridging, state machine control, and board-level glue logic where deterministic timing, low-power standby (5 µA), and PCI compliance are required.
Technical Context
The ATF1508ASV-15QC160 implements a hierarchical CPLD architecture with eight logic chains, each supporting up to 40-product-term sum-of-products logic via cascade paths. Its switch matrix selects up to 40 signals from a global bus fed by all 96 I/Os, four dedicated inputs, and buried feedback from all 128 macrocells.
Each macrocell integrates five product terms (expandable to 40 via cascade), configurable D/T/latch flip-flops, XOR-based arithmetic/comparison logic, and independent output enable with slew-rate control. Global control resources include three GCLK pins, two PD pins, GCLR, OE1/OE2, and JTAG TDI/TMS/TCK/TDO-all mapped to fixed package terminals in the 160-lead PQFP.
Key Specifications

Pinout & Package
ATF1508ASV-15QC160 is housed in a 160-lead Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch, 14 mm × 20 mm body size, and exposed thermal pad (non-electrical). Pin 1 is located at top-left corner; pin numbering proceeds counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–7, 34–40, 44 | No-connect (N/C) | Internally unconnected; must remain floating or tied to GND per PCB layout guidelines - no routing or loading permitted. |
| 8, 26, 55, 61, 79, 104, 133, 143 | VCCIO | I/O power supply pins - each powers local I/O banks; decoupling capacitors (0.1 µF ceramic) required within 5 mm of each VCCIO pin. |
| 17, 42, 60, 66, 95, 113, 138, 148 | GND | Ground reference pins - distributed to minimize ground bounce; must connect to solid ground plane with multiple vias. |
| 63, 159 | I/O/PD1, I/O/PD2 | Power-down control inputs - asserted high to enter sub-5 mA power-down mode; disables all logic transitions while preserving register and output states. |
| 9, 22, 99, 112 | I/O/TDI, I/O/TMS, I/O/TCK, I/O/TDO | JTAG boundary-scan and ISP interface - operate at 3.3V logic levels; TMS/TDI support internal pull-up when enabled in design file. |
| 137 | I/O/GCLK3 | Third global clock input - synchronous to internal logic array; supports edge-triggered register updates and cascaded timing domains. |
| 139–142 | INPUT/GCLK1, INPUT/OE1, INPUT/GCLR, INPUT/OE2/GCLK2 | Dedicated control inputs - GCLK1/GCLK2/GCLK3 provide clock sources; GCLR enables asynchronous reset; OE1/OE2 control global output enables. |
| 141 | INPUT/GCLR | Global asynchronous clear - active-low signal that resets all 128 macrocell flip-flops simultaneously, independent of clock edges. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable pin-keeper | Prevents floating inputs/I/Os by latching last driven state - eliminates external pull-ups and reduces system noise and DC power draw. |
| Individual macrocell power control | Reduced-power bit per macrocell lowers ICC3 by >50% in standby - extends battery life in portable instrumentation without sacrificing logic density. |
| Combinatorial output with registered feedback | Enables dual-latch behavior within single macrocell - supports compact state machines and pipelined datapaths without consuming extra logic resources. |
| Input transition detection (ITD) | Detects rising/falling edges on global clocks, inputs, and I/Os - replaces external edge-detection logic for wake-on-event or pulse-width measurement functions. |
| VCC power-up reset with hysteresis | Large-hysteresis option ensures robust initialization at 3.0V - guarantees known register state after cold start in industrial temperature range (–40°C to +85°C). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1508ASVL-15QC160 | Same die, "L" suffix denotes guaranteed 5 µA standby current; identical pinout, timing, and feature set. | Required where ultra-low standby power is specified in system-level power budget. | Select ATF1508ASVL-15QC160 only if datasheet ICC1(L) = 5 µA is contractually mandated; otherwise ATF1508ASV-15QC160 meets same functional specs. |
| XCR3128XL-10VQ100I | 128-macrocell Xilinx CoolRunner-II CPLD; 10 ns tPD, 3.3V-only, 100-pin VQFP - no PD pins or ITD circuits. | Suitable for cost-sensitive consumer designs where JTAG ISP and power-down are non-critical. | Choose XCR3128XL-10VQ100I only if footprint change is acceptable and reduced-power features are unnecessary. |
Compared with ATF1508ASVL-15QC160, the ATF1508ASV-15QC160 offers identical functionality but with relaxed standby current specification (not guaranteed ≤5 µA); versus XCR3128XL-10VQ100I, it provides superior industrial-grade power management, dedicated power-down pins, and input transition detection - critical for ruggedized embedded control.

FAQ
What is the maximum operating frequency supported by the ATF1508ASV-15QC160?
The ATF1508ASV-15QC160 supports a maximum internal global clock frequency of 76.9 MHz (tCNT = 13 ns minimum period) and a maximum array clock frequency of 76.9 MHz. Its 15 ns pin-to-pin delay enables reliable operation in systems with 66 MHz system clocks, provided setup/hold times (tSU = 11 ns, tH = 0 ns) are met. The actual achievable frequency depends on logic depth and routing; timing analysis must be performed using Atmel's WinCUPL or third-party synthesis tools.
Does the ATF1508ASV-15QC160 require external pull-up resistors on JTAG pins?
No - the ATF1508ASV-15QC160 includes programmable internal pull-up resistors on TMS and TDI pins, which can be enabled during design compilation. When activated, these eliminate the need for external 4.7 kΩ pull-ups, reducing BOM count and PCB area. Pull-up configuration is stored in the JEDEC fuse map and persists across power cycles.
How does the power-down mode function on the ATF1508ASV-15QC160?
When either PD1 or PD2 pin is driven high, the ATF1508ASV-15QC160 enters power-down mode, reducing supply current to <5 mA. All internal logic states and registered outputs are latched and held; tri-stated outputs remain high-Z. Input signals (except PD pins) are blocked, and pin-keeper circuits maintain last-driven I/O states. Recovery occurs within 1 µs after PD pin returns low, with full functionality restored before next clock edge.
Can the ATF1508ASV-15QC160 be used without JTAG functionality?
Yes - JTAG is a programmable option. If boundary-scan testing and in-system programming are not required, the four JTAG pins (TDI, TMS, TCK, TDO) become general-purpose I/Os, increasing usable pin count from 96 to 100. This configuration is selected during JEDEC file generation and permanently fused; JTAG cannot be re-enabled without erasing and reprogramming the entire device.
What packaging and RoHS compliance status applies to the ATF1508ASV-15QC160?
The ATF1508ASV-15QC160 is supplied in a green, Pb/Halide-free, RoHS-compliant 160-lead PQFP package (JEDEC MS-026AC). It meets IPC/JEDEC J-STD-020D moisture sensitivity level 3 (MSL3), requires bake conditioning if exposed to ambient >30°C/60% RH for >168 hours, and is qualified for reflow per IPC/JEDEC J-STD-020.
