For engineers reviewing the ATF1508ASV-15QC100 datasheet, ATF1508ASV-15QC100 pinout, ATF1508ASV-15QC100 application, or ATF1508ASV-15QC100 equivalent, key selection criteria include JTAG ISP capability, programmable slew rate per output, pin-controlled power-down (PD1/PD2), security fuse protection, and compatibility with IEEE 1149.1 boundary-scan testing.
Technical Context
The ATF1508ASV-15QC100 implements a hierarchical routing architecture with a global bus feeding up to 40 signals into each logic block's switch matrix, plus regional foldback buses enabling 40-product-term cascade logic chains. Its macrocell structure integrates five product terms, OR/XOR/CASCADE logic, configurable D/T/latch flip-flops, and buried combinatorial or registered feedback paths.
It supports dual-clock domains (global and array clocks), ITD circuits on global clocks and I/Os, fast registered input from product terms, and VCC power-up reset with selectable hysteresis. The device uses electrically-erasable EEPROM technology with 10,000 program/erase cycles and 20-year data retention, and includes JTAG-based in-system programming and boundary-scan test support.
Key Specifications

Pinout & Package
ATF1508ASV-15QC100 is housed in a 100-lead Thin Quad Flat Package (TQFP) with 0.5 mm pitch, RoHS-compliant, lead-free finish, and thermal pad-compatible footprint. Pin 1 is located at top-left corner (marking dot adjacent), with pins numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 41 | I/O/PD1 | Bi-directional I/O with power-down control - when asserted high (with PD feature enabled), forces device into sub-5 mA power-down state; cannot serve as logic input/output while active. |
| 90, 142 | INPUT/OE2/GCLK2 | Dedicated pin supporting global clock 2, output enable 2, or general input - selected by fitter; enables multi-clock domain synchronization or shared OE control. |
| 89, 141 | INPUT/GCLR | Asynchronous global clear - resets all registers synchronously or asynchronously depending on macrocell configuration; critical for state machine initialization. |
| 87, 139 | INPUT/GCLK1 | Primary global clock input - drives register clocks across all macrocells; supports tSU = 11 ns setup time at -15 speed grade. |
| 85, 137 | I/O/GCLK3 | Third global clock input - expands clock domain flexibility for multi-phase control or peripheral timing isolation. |
| 4, 9 | I/O/TDI | JTAG Test Data Input - serially loads instruction/data into boundary-scan chain or ISP controller; pull-up option available in design. |
| 15, 22 | I/O/TMS | JTAG Test Mode Select - controls TAP controller state transitions; pull-up option prevents floating during power-up. |
| 62, 99 | I/O/TCK | JTAG Test Clock - synchronous clock for boundary-scan and ISP operations; requires stable 50% duty cycle. |
| 73, 112 | I/O/TDO | JTAG Test Data Output - serially outputs scan data or ISP status; high-impedance when not active. |
| GND (8 pins) | Ground | Eight dedicated ground connections - ensures low-noise reference and robust ESD current path (200 mA latch-up immunity). |
| VCCIO (8 pins) | I/O Power Supply | Separate 3.3V I/O rail - decouples I/O switching noise from core logic; supports mixed-voltage interfacing when combined with VCCINT. |
| VCCINT (2 pins) | Core Power Supply | Internal logic voltage rail - powers macrocell logic array and registers; must be decoupled near package center for signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Slew Rate per Output | Enables noise reduction by slowing non-critical outputs; default slow mode avoids EMI issues without requiring external RC networks. |
| Pin-keeper Circuits | Prevents floating inputs/I/Os after release - eliminates need for external pull-ups, reduces DC leakage, and suppresses system noise in unconnected states. |
| Three Global Clock Inputs | Supports independent clock domains for control, data, and interface logic - simplifies timing closure in multi-function systems without external clock muxing. |
| Security Fuse Protection | Blocks unauthorized read-back of fuse pattern while preserving User Signature access - protects IP in deployed firmware or configuration bitstreams. |
| ITD Circuits on Clocks & I/O | Detects input transitions for edge-triggered wake-up or glitch filtering - enables low-power event-driven operation without CPU polling. |
| VCC Power-up Reset with Hysteresis | Ensures deterministic register initialization at power-on; Large hysteresis option recommended for 3.0V operation to prevent metastability. |

FAQ
What is the operating voltage range for the ATF1508ASV-15QC100?
The ATF1508ASV-15QC100 operates across a 3.0V to 3.6V supply range for both VCCIO and VCCINT rails. This 3.3V nominal tolerance accommodates standard industrial power rails and ensures compatibility with TTL- and CMOS-level interfaces. Operation below 3.0V is not guaranteed and may impair timing margins or cause power-up reset failures - especially when the Large hysteresis option is enabled.
Does the ATF1508ASV-15QC100 support in-system programming (ISP)?
Yes, the ATF1508ASV-15QC100 supports full in-system programming via its 4-pin JTAG interface compliant with IEEE Std. 1149.1. Programming can be performed without removing the device from the PCB using SVF files, Atmel-provided tools, or third-party ATE systems. The JTAG pins (TDI, TMS, TCK, TDO) double as I/O when JTAG is disabled in the design file.
How many global clock inputs does the ATF1508ASV-15QC100 have?
The ATF1508ASV-15QC100 has three dedicated global clock inputs: GCLK1 (pin 87/139), GCLK2 (pin 90/142), and GCLK3 (pin 85/137). Each can drive register clocks independently, enabling multi-domain timing architectures. GCLK1 is typically used as the primary clock; GCLK2 and GCLK3 support secondary control paths or peripheral synchronization.
What is the purpose of the PD1 and PD2 pins on the ATF1508ASV-15QC100?
The PD1 and PD2 pins on the ATF1508ASV-15QC100 enable optional pin-controlled power-down mode. When asserted high (and enabled in the design), they reduce supply current to <5 mA while latching all internal logic and output states. During power-down, inputs (except PD pins) are blocked, and I/O hold latches maintain pin levels - making it ideal for low-power sleep modes in battery-operated systems.
Is the ATF1508ASV-15QC100 RoHS compliant?
Yes, the ATF1508ASV-15QC100 is RoHS compliant and offered in green (Pb/Halide-free) packaging. The 100-lead TQFP package meets EU Directive 2011/65/EU requirements and carries appropriate marking per Microchip's compliance documentation. No exemptions apply, and lead-free solder reflow profiles are validated per JEDEC J-STD-020.
