EPM570T144I5 Visão geral
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between discrete glue-logic ICs (74-series gates) and large SRAM FPGAs in the logic-hierarchy. CPLDs use flash or EEPROM configuration cells and a classic AND-OR PLA-style macrocell fabric, delivering deterministic timing, instant-on behavior (typically <1 ms wake-up), and high drive strength. CPLDs are widely used as interface bridges, bus controllers, address decoding, and power-up sequencers, where their deterministic timing and zero-config-latency offer advantages over SRAM FPGAs that require external boot memory and a multi-millisecond configuration phase.
Key features of the EPM570T144I5 include 440 logic elements (macrocells), 8 Kbits of user flash memory (UFM), 116 user I/O, JTAG IEEE 1149.1 boundary-scan support, and multi-voltage I/O support across 1.5 V to 3.3 V standards. The 'I' suffix denotes the industrial temperature range (-40 °C to +100 °C junction), and the '5' speed grade corresponds to the 5.4 ns tPD1 timing specification. MultiCore architecture and Quartus II / Intel Quartus Prime design support enable straightforward design entry, synthesis, and in-system programming via JTAG.
Typical applications include I/O expansion and bus bridging in industrial control, glue-logic consolidation in telecom line cards, address decoding and interrupt steering in embedded SBCs, and power-sequencing networks in ATCA/uTCA platforms. The non-volatile, instant-on nature also makes the EPM570T144I5 well suited to safety-critical applications where deterministic post-reset behavior is mandatory, and to low-volume ASIC replacement scenarios where NRE costs of an ASIC are not justified.
When designing with the EPM570T144I5, observe I/O bank grouping rules - all I/O in a bank must share a single VCCIO supply - and budget at least four dedicated GND pins plus one decoupling capacitor pair (0.1 µF + bulk) per bank. The TQFP-144 exposed-pad footprint requires a continuous ground plane beneath the package to meet the 4-layer PCB thermal envelope.

Aplicações típicas
EPM570T144I5 é adequado para 6 aplicaçãos: Industrial Control I/O Expansion & Bus Bridging, Telecom Line Card Glue Logic, Power-Up Sequencer for Multi-Rail Systems, ASIC/Discrete-Logic Consolidation, Embedded SBC Address Decoding & Interrupt Routing, Test & Measurement Instrumentation Front-End.
Industrial Control I/O Expansion & Bus Bridging
The EPM570T144I5's 116 user I/O and 440 macrocells make it well suited to industrial control designs that need to bridge between legacy parallel buses (ISA, PC/104, address/data demultiplexed buses) and modern microcontrollers. Its 5.4 ns tPD1 supports glue-logic timing paths up to roughly 185 MHz, sufficient for synchronous address decoding and chip-select generation. Instant-on from non-volatile storage avoids bootloader complications when an MCU has crashed, allowing the CPLD to drive deterministic reset vectors. With the industrial -40 °C to +100 °C temperature range, the part is suitable for factory-floor equipment and outdoor controllers.
Recomendado
Telecom Line Card Glue Logic
Telecommunications line cards require deterministic, fast response to interrupt, clock, and reset events. The EPM570T144I5's deterministic timing (no SRAM-config latency), 5.4 ns pin-to-pin delay, and JTAG-driven ISP simplify board bring-up and field firmware updates. The multi-voltage I/O banks (1.5 V to 3.3 V) directly interface legacy 3.3 V line-card ASICs alongside newer 1.8 V DSPs and SERDES chips without external level shifters. Use cases include backplane address decoding, TDM bus multiplexing, and clock distribution gating for ATCA/uTCA platforms.
Recomendado
Power-Up Sequencer for Multi-Rail Systems
When system boards require strict power-up and power-down sequencing of multiple rails (e.g., 0.9 V core, 1.5 V DDR, 2.5 V analog, 3.3 V I/O), the EPM570T144I5 provides a deterministic sequencing engine. Its non-volatile flash configuration ensures that on every power cycle the same sequence is enforced within microseconds - critical for ASICs, FPGAs, and processors that require core-before-I/O rails. The 116 I/O are sufficient to drive dozens of enable pins and PG signals. Compared with MCU-based sequencers, the CPLD adds no firmware-update risk and boots in <1 ms.
Recomendado
ASIC/Discrete-Logic Consolidation
Designs that historically used dozens of 74-series logic gates, multiplexers, and PAL/GAL devices can consolidate the entire logic block into a single EPM570T144I5, reducing PCB area, BOM cost, and assembly time. With 440 macrocells, the device typically replaces 30-60 discrete SSI/MSI packages. The instant-on flash configuration means no boot PROM is needed, and JTAG ISP allows post-assembly logic changes without reworking the board. The TQFP-144 footprint is well suited to 4-layer designs with standard surface-mount assembly lines.
Recomendado
Embedded SBC Address Decoding & Interrupt Routing
Single-board computers (SBCs) and ARM/MIPS-based compute modules often need flexible chip-select and interrupt routing between the host CPU and peripheral chips. The EPM570T144I5's 5.4 ns propagation delay supports decoding at 100 MHz+ host bus speeds, and its 116 I/O easily accommodate 8-16 peripheral chip selects plus 16-32 interrupt/gpio lines. The industrial temperature grade and surface-mount TQFP-144 package are well matched to SBC-style designs with passive cooling. Quartus Prime Lite provides a free development environment.
Recomendado
Test & Measurement Instrumentation Front-End
Test and measurement equipment (logic analyzers, protocol exercisers, JTAG/boundary-scan controllers) often needs custom stimulus/response logic tightly coupled to an analog front end. The EPM570T144I5 offers 116 user I/O with 5.4 ns timing to drive pattern generators, mux/demux control signals, and trigger logic. Its instant-on behavior eliminates calibration drift after power cycling, and the JTAG interface allows remote in-system firmware updates in deployed test racks. The industrial temperature range covers most lab and field environments.

Notas de projeto
The EPM570T144I5 requires a clean 1.8 V supply on VCCINT pins (43 and 116) and separate VCCIO supplies for each of the four I/O banks (1.5 V / 1.8 V / 2.5 V / 3.3 V). Place a 0.1 µF X7R ceramic decoupling capacitor within 3 mm of every VCC pin, plus a 10 µF bulk capacitor at the regulator output. The device does not require a specific power-up sequence between VCCINT and VCCIO, but all VCC rails must reach their nominal values within 100 ms to ensure proper configuration from flash. Estimated: at fMAX=304 MHz with all 116 I/O switching, dynamic core current can reach ~80 mA.
The TQFP-144 package has a 0.5 mm pitch and a 20 x 20 mm body, requiring a 4-layer PCB with continuous ground and power planes to meet signal-integrity requirements above 100 MHz. Maintain 50-ohm controlled impedance on critical nets (clock, JTAG) and use 8-mil traces with 8-mil spacing. Place the JTAG header (TCK/TMS/TDO/TDI) on the board edge for in-system programming access. Thermal performance is adequate for typical industrial designs without an explicit heatsink, but a 2 x 2 cm copper pour on the top layer beneath the package is recommended.
Do not leave JTAG pins (TCK, TMS, TDI, TDO) floating - tie TDI and TMS high through 10 kohm pull-ups to VCCIO, and pull TCK low through 10 kohm to GND. Floating JTAG pins can cause ISP failure or unpredictable configuration reload on power-up. Also: the MAX II device configures on every power-up from internal flash, so VCCINT must ramp monotonically; use a supervisor IC if your power tree has soft-start edges. I/O banks must not be left unpowered - unused banks should have their VCCIO tied to a valid rail (1.5 V to 3.3 V) to prevent I/O leakage through floating ESD structures.
Estimated: under worst-case industrial conditions (Tj=100 °C) with all 116 I/O driving 8 mA loads at 50 MHz, total power dissipation is approximately 0.5-0.8 W. The TQFP-144 package has a junction-to-ambient thermal resistance of roughly 35 °C/W on a standard 4-layer JEDEC test board, giving a junction-to-ambient temperature rise of 17-28 °C above ambient. The 'I' industrial temperature grade supports -40 °C to +100 °C junction, sufficient for most sealed enclosure designs. Provide an explicit copper pour or thermal via array beneath the exposed pad area (TQFP-144 has no exposed pad, but top-layer copper flood is recommended).
