Product details
Overview
ATF1508AS-10QC100 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-based in-system programmability, PCI compliance, and dual-voltage I/O (3.3 V or 5.0 V) for integration into legacy and modern digital control systems.
For engineers reviewing the ATF1508AS-10QC100 datasheet, ATF1508AS-10QC100 pinout, ATF1508AS-10QC100 application, or ATF1508AS-10QC100 equivalent, key selection criteria include its 100-pin TQFP package, 5 V core supply with 3.3/5.0 V I/O flexibility, programmable power-down via PD1/PD2 pins, and IEEE 1149.1 boundary-scan test support.
Technical Context
The ATF1508AS-10QC100 implements a hierarchical routing architecture with global and regional buses: all 128 macrocell outputs and all I/O/input signals feed a global bus, from which up to 40 signals are selected per logic block via software-controlled switch matrices. Each macrocell generates a foldback term routed to a regional bus serving 16 adjacent macrocells, enabling high-fan-in sum-of-products logic with cascaded chains of up to 40 product terms.
Its macrocell supports D/T/latch flip-flops with individually configurable clock (GCLK or product-term derived), asynchronous reset/preset, and output enable sourced from dedicated OE pins, I/O pins, or macrocell outputs. Input transition detection (ITD) circuits on global clocks, inputs, and I/Os enable edge-sensitive wake-up and low-power event triggering without external logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1508ASV-10QC100 | Same logic architecture and pinout; differs only in speed grade (-10 vs -15) and voltage tolerance (supports 3.3 V core in "V" variant). | Targeted at lower-power, 3.3 V-only systems where core voltage reduction is mandatory; not drop-in compatible due to VCCINT requirement difference. | Select only if migrating to 3.3 V core supply and verified timing closure at -10 speed grade. |
| EPM7128SLC84-10 | Intel MAX 7000S CPLD with 128 macrocells but 84-pin PLCC package; lacks ITD, pin-keeper, and PCI compliance; different JTAG BSDL. | Suitable for cost-sensitive, non-PCI, non-industrial applications where TQFP footprint and advanced power features are not required. | Choose when footprint flexibility and legacy PLCC assembly infrastructure exist; verify timing and feature parity before migration. |
Compared with ATF1508ASV-10QC100, the ATF1508AS-10QC100 requires 5 V core supply but delivers higher drive strength and PCI compliance; versus EPM7128SLC84-10, it offers superior routing density, integrated power management, and TQFP packaging - making it preferable for space-constrained, thermally demanding, or standards-compliant designs.

FAQ
What is the core supply voltage requirement for ATF1508AS-10QC100?
The ATF1508AS-10QC100 requires a 5.0 V ±5% supply on VCCINT pins. This is non-negotiable: VCCINT must be 5 V regardless of I/O voltage selection. VCCIO may be set to either 3.3 V or 5.0 V independently, enabling mixed-voltage interfacing. Using incorrect VCCINT risks functional failure or permanent damage, as confirmed in Absolute Maximum Ratings and DC Operating Conditions sections of the official datasheet.
Does ATF1508AS-10QC100 support in-system programming (ISP)?
Yes, ATF1508AS-10QC100 fully supports IEEE 1149.1-compliant in-system programming via its four-pin JTAG interface (TCK, TMS, TDI, TDO). Programming can be performed without removing the device from the PCB using standard SVF files, Atmel ISP software, or third-party ATE tools. The JTAG port remains accessible even after security fuse programming, though fuse verification is disabled - the ATF1508AS-10QC100 retains full ISP capability throughout its lifecycle.
How many global clock inputs does ATF1508AS-10QC100 provide?
The ATF1508AS-10QC100 provides three dedicated global clock inputs: GCLK1, GCLK2, and GCLK3. These pins are physically distinct and electrically isolated, allowing independent clock domains for different logic partitions. Each can drive any macrocell's clock input directly or via product-term gating, and all support Input Transition Detection (ITD) for edge-triggered wake-up - a feature explicitly documented for GCLK1–GCLK3 in the Enhanced Features section of the datasheet.
Can ATF1508AS-10QC100 operate in both 3.3 V and 5.0 V I/O environments simultaneously?
No - ATF1508AS-10QC100 supports either 3.3 V or 5.0 V on all VCCIO pins simultaneously, not mixed voltages per pin. The device has a single VCCIO supply rail shared across all I/O banks. To interface with both 3.3 V and 5.0 V peripherals, external level-shifting circuitry or careful system partitioning is required. This constraint is clearly stated in the "3.3V or 5.0V I/O Operation" section and reflected in the pinout diagrams showing unified VCCIO connections.
What is the purpose of the PD1 and PD2 pins on ATF1508AS-10QC100?
PD1 and PD2 are active-high, pin-controlled power-down enable inputs. When asserted (driven high), they place the ATF1508AS-10QC100 into a sub-10 mA standby state while preserving all register contents and output states. This feature is enabled during design compilation and disables the affected macrocell's logic array input - though buried feedback and cascade logic remain usable. The behavior and timing parameters (e.g., tIVDH, tDLIV) are fully specified in the Power-down AC Characteristics table.
