Product details
Overview
ATF1508ASV-15AU100-T 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, and is packaged in a 100-lead TQFP for embedded control and glue-logic replacement in industrial automation systems.
For engineers reviewing the ATF1508ASV-15AU100-T datasheet, ATF1508ASV-15AU100-T pinout, ATF1508ASV-15AU100-T application, or ATF1508ASV-15AU100-T equivalent, key selection criteria include its JTAG-based in-system programmability, programmable slew rate per output, pin-keeper input retention, and dual power-down pins (PD1/PD2) enabling sub-5 mA standby current in "L"-mode configurations.
Technical Context
The ATF1508ASV-15AU100-T 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 and 128 macrocell feedbacks.
Each macrocell integrates five product terms, configurable D/T/latch flip-flops, XOR-based arithmetic/compare logic, and foldback regional bus routing. Global control signals-GCLK1–3, GCLR, OE1/OE2-are individually assignable per macrocell, and ITD (Input Transition Detection) circuits are present on all global clocks and I/Os.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 128 macrocells - provides gate-equivalent capacity for replacing multiple 74-series TTL/MSI functions or legacy PLDs in compact control logic. |
| Propagation Delay | 15 ns max pin-to-pin - enables reliable timing closure at 66 MHz system clock rates with margin for board-level skew. |
| Operating Voltage | 3.0 V to 3.6 V - compatible with 3.3 V LVTTL/LVCMOS I/O standards and industrial power rails without level-shifting. |
| Max Clock Frequency | 77 MHz registered operation - supports real-time state machine execution and synchronous data path control in motor drives and sensor interfaces. |
| Package | 100-lead TQFP (14 × 14 mm, 0.5 mm pitch) - surface-mount footprint optimized for automated assembly and thermal dissipation in enclosed enclosures. |
| JTAG Compliance | IEEE Std. 1149.1-1990 & 1149.1a-1993 - enables boundary-scan testing, in-system programming, and BSDL-based fault isolation without test fixtures. |
| Power Management | 5 µA standby (L-mode), pin-controlled 100 µA power-down - reduces idle power in battery-backed or energy-sensitive industrial nodes. |
Pinout & Package
ATF1508ASV-15AU100-T is housed in a 100-lead Thin Quad Flat Package (TQFP) with 0.5 mm lead pitch and exposed thermal pad. Pin 1 is located at top-left corner (marking dot adjacent), and the package is RoHS-compliant, Pb-free, and halide-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 41 | I/O/PD1, I/O/PD2 | Dual pin-controlled power-down inputs - assert high to enter sub-5 mA low-power mode; disables all logic transitions except PD pin monitoring. |
| 4, 15, 62, 73 | I/O/TDI, I/O/TMS, I/O/TCK, I/O/TDO | JTAG boundary-scan and ISP interface - enables programming, debug, and interconnect test without removing device from PCB. |
| 87, 89, 90 | I/O/GCLK3, INPUT/GCLR, INPUT/OE1 | Global control resources - GCLK3 feeds register clocks; GCLR provides asynchronous reset; OE1 enables output drivers globally. |
| 85, 92, 142 | I/O/GCLK3, INPUT/OE2/GCLK2, INPUT/GCLK1 | Three independent global clock inputs - allow multi-domain timing, clock domain crossing, or redundant clock sourcing in safety-critical logic. |
| 13, 20, 36, 41, 53, 68, 84, 93 | VCCIO | I/O power supply pins - decoupled per quadrant to suppress switching noise and support mixed-voltage I/O interfacing. |
| 11, 26, 38, 43, 59, 74, 86, 95 | GND | Eight dedicated ground pins - minimize ground bounce and ensure stable reference for high-speed I/O transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable slew rate per output | Reduces EMI and signal integrity issues on long traces by allowing slow switching on non-critical outputs while maintaining fast edges on timing-critical paths. |
| Pin-keeper circuitry on all I/Os | Eliminates need for external pull-up/down resistors on unused inputs, preventing floating states, leakage-induced power waste, and system noise in unpopulated I/O banks. |
| Three global clock inputs with ITD | Enables glitch-free clock domain synchronization and transition-triggered event capture (e.g., encoder edge detection) without consuming macrocell resources. |
| Buried registered feedback in combinatorial outputs | Allows dual-latch behavior within a single macrocell - critical for implementing pipelined logic, metastability-hardened synchronizers, or compact state machines. |
| Security fuse + 16-bit User Signature | Protects design IP from reverse engineering; User Signature field stores revision ID, project name, or calibration data accessible even when security fuse is blown. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3256XL-10TQ144I | 256 macrocells, 10 ns speed grade, 3.3 V only, no built-in power-down pins | Higher density but lacks pin-controlled low-power mode and ITD circuits | Select for higher logic capacity where ultra-low standby current is not required. |
| ISPLSI2096VE-100LT100 | 96 macrocells, 100-pin TQFP, 3.3 V, non-JTAG ISP (SRAM-based, requires external config PROM) | No IEEE 1149.1 boundary-scan; relies on proprietary programming interface | Select when JTAG test infrastructure is unavailable and design uses external configuration memory. |
Compared with XCR3256XL-10TQ144I and ISPLSI2096VE-100LT100, the ATF1508ASV-15AU100-T delivers optimal balance of density, low-power control granularity, and standardized JTAG accessibility - making it preferred for cost-sensitive, field-upgradable industrial controllers requiring robust testability and sub-10 µA quiescent current.

FAQ
What is the maximum operating frequency of the ATF1508ASV-15AU100-T?
The ATF1508ASV-15AU100-T supports registered logic operation up to 77 MHz, with AC characteristics specifying a maximum internal global clock frequency of 76.9 MHz at the -15 speed grade. This is validated under worst-case conditions (VCC = 3.0 V, TA = 85°C) and assumes proper PCB layout and decoupling. The actual achievable system frequency depends on logic depth, routing congestion, and clock domain constraints in the user design.
Does the ATF1508ASV-15AU100-T support in-system programming (ISP)?
Yes, the ATF1508ASV-15AU100-T 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 standard SVF files, Atmel-provided tools, or third-party ATE systems. JTAG pins (TDI, TMS, TCK, TDO) may be repurposed as general I/O if ISP and boundary-scan are disabled in the design file.
What power-saving features does the ATF1508ASV-15AU100-T offer?
The ATF1508ASV-15AU100-T offers three distinct low-power modes: automatic 5 µA standby (L-version), pin-controlled 100 µA power-down (via PD1/PD2), and per-macrocell reduced-power bit. The latter adds tRPA (10–13 ns) to timing paths but cuts dynamic current significantly. All modes preserve register and output states, and pin-keeper circuits prevent floating inputs during sleep.
Can the ATF1508ASV-15AU100-T replace older PLDs like the 22V10?
Yes, the ATF1508ASV-15AU100-T is explicitly positioned as a functional and pin-compatible upgrade for 22V10 and similar PAL devices. Its 128 macrocells, 100-input global bus, and flexible macrocell architecture support direct migration of fuse-map-based designs. Migration tools and POF-to-JED conversion utilities are provided by Microchip to streamline legacy replacement.
Is the ATF1508ASV-15AU100-T RoHS-compliant and green-packaged?
Yes, the ATF1508ASV-15AU100-T is manufactured in a green (Pb/Halide-free/RoHS-compliant) 100-lead TQFP package. It meets JEDEC J-STD-020 moisture sensitivity level 3 and is qualified for industrial temperature range (-40°C to +85°C). Full compliance documentation, including material declarations and test reports, is available through Microchip's quality portal.
