EPM7256AEFC100-7 概要
A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that sits between discrete 74-series glue logic and larger FPGAs. It is typically used to implement boot-time-immune decode logic, I/O expander bridges, bus-arbitration state machines, and address-latching interfaces, and it boots in milliseconds because configuration is stored in on-chip EEPROM rather than loaded from external flash.
Key features include in-system programmability via IEEE 1149.1 JTAG, 5 V tolerant I/O, programmable power management with pin-per-pin enable/disable, and four global clock networks with product-term or I/O-pin control. Each macro cell contains a programmable AND/OR array with a register that can be configured as D, T, JK, or SR flip-flop, and the 256 macro cells are partitioned into 16 Logic Array Blocks for efficient partitioning of wide decode and arithmetic functions.
The MAX 7000A architecture combines an EEPROM-based configuration memory (true non-volatility - no external boot PROM) with a MultiVolt core and MultiVolt I/O interface, allowing the core to operate at 3.3 V while the I/O banks interface directly to 2.5 V, 3.3 V, or 5 V devices. The 100-pin FBGA offers a compact footprint that suits high-density PCB designs where TQFP variants would be too large.
Typical applications span industrial control boards, telecom base-station glue logic, PCI/ISA bus decode in legacy industrial backplanes, address decoding in 32-bit embedded systems, and prototype ASIC replacement. Designers choose the MAX 7000A family for instant-on behavior, deterministic timing, and a known-silicon IP portfolio that has shipped for decades.
When designing with this part, observe the 3.3 V VCCINT supply (separate from VCCIO if MultiVolt is used), keep JTAG chain lengths short, and respect the 100-FBGA thermal pad layout recommended in the Intel MAX 7000A device handbook. Decoupling the eight VCCINT and four VCCIO balls with 0.1 uF X7R ceramics placed within 3 mm of each ball cluster is recommended for reliable in-system programming.

主な用途
EPM7256AEFC100-7 の用途: 6 件s: PCI/ISA Bus Decode and Address Latching, Industrial Control Board Glue Logic, Telecom Base Station Backplane Logic, ASIC Prototype and Pre-Production Bridge, Legacy Embedded System Address Decoder, I/O Expander and Bus Bridge for Microcontroller Boards.
PCI/ISA Bus Decode and Address Latching
The EPM7256AEFC100-7's 256 macro cells, 7.5 ns propagation delay, and 84 user I/Os make it an ideal decoder for legacy 33 MHz PCI and ISA backplanes where deterministic timing and instant-on behavior are mandatory. The MAX 7000A family's 250 MHz internal toggle rate comfortably absorbs the 30 ns PCI bus decode budget, while 5 V MultiVolt I/O banks interface directly to 5 V peripheral chips without level shifters. Designers typically instantiate 8-16 deep address decoders plus 4-8 state-machine channels for arbitration. Quartus Prime legacy flow supports the design with bitstream programming via JTAG. Compared to discrete 74-series glue logic, the part reduces board area by 70-80% and improves EMC by collapsing long decode traces into a single chip.
おすすめ
Industrial Control Board Glue Logic
Factory automation PLCs and motor controllers use the EPM7256AEFC100-7 to consolidate 30-60 discrete 74HC/74LVC logic gates into a single instant-on programmable device. The part's 5 V-tolerant MultiVolt I/O bridges 3.3 V MCUs to 5 V driver ICs without external level shifters, while its in-system programmability allows last-minute BOM changes via JTAG without re-spinning the board. Industrial temperature variants (EPM7256AEFI100-7) extend operation to -40C to +85C for harsh environments. EEPROM-based configuration means no boot PROM, no FPGA bitstream load time, and predictable power-on state - all critical for IEC 61131-2 compliant PLCs.
おすすめ
Telecom Base Station Backplane Logic
The EPM7256AEFC100-7 is widely deployed in telecom backplanes for E1/T1 framer interface glue, HDLC channel aggregation, and timing-reference distribution. Its deterministic 7.5 ns tPD and 250 MHz toggle rate handle 8.192 MHz E1 and 1.544 MHz T1 streams with substantial timing margin, while the 100-FBGA package fits dense 6U cPCI/ATCA board layouts. The non-volatile EEPROM configuration survives board-level power cycles without external boot devices, and JTAG in-system programming enables firmware updates on deployed hardware. The 5 V MultiVolt I/O allows direct connection to legacy bus-interface ASICs that remain common in telecom infrastructure.
おすすめ
ASIC Prototype and Pre-Production Bridge
Design teams use the EPM7256AEFC100-7 as a stand-in for missing or in-development ASICs, prototyping board interfaces months before mask tape-out. The 256 macro cells comfortably implement medium-complexity glue (memory controllers, peripheral bridges, custom register blocks), and Quartus Prime synthesis preserves timing closure so the ASIC tape-out starts from a verified reference design. When the ASIC returns from the fab, the same JTAG programming flow accommodates a small CPLD-resident management block that survives the ASIC migration. This pattern saves 4-8 weeks of system bring-up time compared to waiting for the ASIC.
おすすめ
Legacy Embedded System Address Decoder
The EPM7256AEFC100-7 integrates 32-bit address decoders for 68k, MIPS, ARM7, and PowerPC embedded hosts in single-chip form. Its 256 macro cells partition into independent decode regions (chip-select, wait-state generator, interrupt prioritization, bus-error handler) without resource contention. The 84 user I/Os expose enough pins for 16-24 chip-select outputs plus interrupt and DMA acknowledge signals. Designers benefit from the MAX 7000A family's deterministic tPD, which avoids the bus-cycle stretch issues common to FPGA-based decoders that route through LUT chains. Quartus legacy flow supports all classic embedded CPU glue patterns.
おすすめ
I/O Expander and Bus Bridge for Microcontroller Boards
8-bit and 16-bit microcontroller boards use the EPM7256AEFC100-7 as an SPI/I2C-to-parallel I/O expander, gaining 30-60 additional GPIO bits with bit-bangable direction and pull-up control. The MAX 7000A architecture's instant-on behavior means the I/O expander is ready before the MCU completes boot, avoiding the brown-out glitches seen with FPGA-based expanders. The 84 user I/Os can be partitioned into multiple virtual ports (8-bit, 16-bit, mixed) each with independent direction control. Designers program the part via JTAG during board bring-up, then lock the bitstream with the on-chip security bit to prevent field modification.

設計ノート
Estimated: at fMAX = 126.6 MHz with 84 I/Os toggling, ICCINT draws approximately 30-50 mA from the 3.3 V VCCINT rail. Decouple each VCCINT ball cluster with a 0.1 uF X7R ceramic placed within 3 mm of the ball. Use a shared 10 uF tantalum or ceramic bulk capacitor at the regulator output. If MultiVolt is enabled, each VCCIO bank (VCCIO1, VCCIO2) requires its own 0.1 uF + 10 uF decoupling pair to suppress simultaneous-switching noise (SSN) on the 5 V-tolerant I/O.
The 100-FBGA at 11x11 mm uses 1.0 mm ball pitch, which requires 0.5 mm via-pad and 0.2 mm trace/space rules on a 4-layer PCB. Fanout the inner-row power and ground balls with short dog-bone or via-in-pad microvias for low inductance. Keep JTAG chain (TCK/TMS/TDI/TDO) traces short and well-spaced from switching I/O to avoid programming glitches. The MAX 7000A device handbook recommends a continuous ground plane on layer 2 for SSN suppression.
Drive 5 V TTL loads from the MultiVolt I/O banks at VCCIO = 5 V with no external pull-ups. For 33 MHz PCI applications, source-terminate clock traces with 33 ohm series resistors at the CPLD output to damp reflections. When bridging to 2.5 V LVCMOS2 devices, set the relevant VCCIO bank to 2.5 V and avoid 5 V signal injection - the MultiVolt interface is unidirectional (5 V tolerant input, but VOH will not reach 5 V from a 2.5 V bank).
Do not confuse EPM7256AEFC100-7 (commercial temp, SnPb) with EPM7256AEFI100-7 (industrial temp) or EPM7256AEFC100-7N (Pb-free) - the package and pinout are identical but the qualification levels differ. The -7 speed grade (7.5 ns tPD) is the fastest; using -10 instead may violate 33 MHz PCI timing. Always program the security bit in production to lock the bitstream against field read-back, and verify the JTAG chain with the Quartus Prime programmer before generating the final bitstream.
