Overview
ATF1508AS-10QC160 from Microchip Technology (formerly Atmel) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 128 macrocells, 5 product terms per macrocell expandable to 40, 7.5 ns pin-to-pin delay, and support for 125 MHz registered operation. It features JTAG boundary-scan (IEEE 1149.1), in-system programmability (ISP), PCI compliance, and dual-voltage I/O (3.3 V or 5.0 V) - deployed in industrial control logic, legacy interface bridging, and FPGA configuration glue logic.
For engineers reviewing the ATF1508AS-10QC160 datasheet, ATF1508AS-10QC160 pinout, ATF1508AS-10QC160 application, or ATF1508AS-10QC160 equivalent, key selection criteria include its 160-pin PQFP package, 10 ns speed grade (-10), 5 V core supply (VCCINT), flexible I/O voltage (VCCIO), power-down capability via PD1/PD2 pins, and macrocell-level reduced-power configuration.
Technical Context
The ATF1508AS-10QC160 implements a hierarchical CPLD architecture with eight logic blocks, each fed by a global bus carrying up to 100 signals (I/Os + buried macrocell feedback) and a regional foldback bus supporting 16-macrocell cascades. Its macrocell structure integrates five product-term logic, OR/XOR/CASCADE logic, D/T/latch-configurable flip-flops, and programmable output enable/slew rate.
It supports three global clock inputs (GCLK1–GCLK3), input transition detection (ITD) on clocks/inputs/I/Os, programmable pin-keeper circuits, VCC power-up reset with selectable hysteresis, and security fuse protection. The device operates with VCCINT = 5.0 V (core) and VCCIO configurable for 3.3 V or 5.0 V I/O drive levels, enabling mixed-voltage system integration.

FAQ
What is the operating temperature range for the ATF1508AS-10QC160?
The ATF1508AS-10QC160 is qualified for industrial temperature operation from –40°C to +85°C. This rating is confirmed in the Absolute Maximum Ratings and DC Operating Conditions sections of the official datasheet (Rev. 0784P–PLD–7/05), and applies specifically to the QC160 package variant. The device maintains full functionality-including JTAG ISP, power-down mode, and PCI drive compliance-across this full range.
Does the ATF1508AS-10QC160 support in-system programming (ISP)?
Yes, the ATF1508AS-10QC160 supports full IEEE 1149.1-compliant in-system programming via its dedicated TCK/TMS/TDI/TDO pins. Programming is performed using 5 V TTL-level signals, and the device ships erased and ready for ISP. The ATF1508AS-10QC160 also supports Serial Vector Format (SVF) files for ATE integration, and third-party tools like Atmel's ISP software or compatible boundary-scan programmers.
Can the ATF1508AS-10QC160 operate with both 3.3 V and 5.0 V I/O simultaneously?
No - the ATF1508AS-10QC160 supports either 3.3 V or 5.0 V I/O operation, selected by the VCCIO supply voltage. VCCIO must be set to a single value (2.7–3.6 V for 3.3 V mode; 4.75–5.25 V for 5.0 V mode), and all I/Os share that voltage rail. However, VCCINT remains fixed at 5.0 V, allowing safe interfacing with 3.3 V inputs even when VCCIO = 5.0 V.
What is the purpose of the PD1 and PD2 pins on the ATF1508AS-10QC160?
The PD1 and PD2 pins on the ATF1508AS-10QC160 provide pin-controlled power-down functionality. When enabled in the design file and driven high, either pin reduces device supply current to <10 mA. During power-down, all internal logic states and registered outputs are latched and held, and I/Os retain their last valid state or high-Z condition - enabling ultra-low-power sleep modes in battery-backed or automotive applications.
Is the ATF1508AS-10QC160 RoHS compliant and halogen-free?
Yes, the ATF1508AS-10QC160 is offered in green (Pb/Halide-free/RoHS-compliant) package options, as explicitly stated in the "Features" section of the datasheet. The 160-lead PQFP package meets EU RoHS Directive 2011/65/EU and JEDEC JS709B halogen-free requirements, with bromine and chlorine content <900 ppm total.
