EPM3512AFC256-18 概要
A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on logic device that combines multiple PAL-like macrocell blocks with a central interconnect matrix, bridging the gap between discrete 74-series glue logic and high-density FPGAs. Within the broader programmable logic taxonomy, the MAX 3000A family sits below FPGAs in density but offers deterministic timing, zero-configuration latency, and high I/O drive strength that make it ideal for bus decoding, address decoding, state-machine control, and power-up sequencer applications. It belongs to the larger class of programmable logic devices (PLDs) within the semiconductor hierarchy.
Key features of the EPM3512AFC256-18 include 512 macrocells distributed across 16 Logic Array Blocks (LABs), a maximum of 212 user I/O pins, and the Fast-Function (FF) input register path that delivers the 18 ns tPD1 timing specification. Each macrocell provides a programmable register with D, T, JK, or SR flip-flop modes, a programmable product-term array of 32 to 64 terms per macrocell, and selectable global or local clocking. The device includes an IEEE Std. 1149.1 JTAG boundary-scan interface and the MultiVolt I/O feature, allowing each I/O bank to interface independently with 2.5 V, 3.3 V, or 5.0 V devices.
Architecturally, the MAX 3000A family uses a hierarchical interconnect called the Programmable Interconnect Array (PIA), which routes signals between any LAB and any I/O pin without contention. The non-volatile EEPROM configuration cell enables true zero-power standby and instant-on behavior at power-up, eliminating the need for external boot memory. The 256-ball BGA package provides a 1.0 mm pitch, enabling compact board layouts for high-density designs.
Typical applications for the EPM3512AFC256-18 include glue-logic consolidation in industrial controllers, register-based peripheral interfacing on legacy PCI/ISA platforms, address decoding for memory subsystems, and bus-width translation between 8-bit, 16-bit, and 32-bit processors. It is also deployed as a power-supply sequencer and reset-distribution controller in ATCA/uTCA and network switches where deterministic power-up behavior is required.
When designing with this device, ensure that VCCINT (3.3 V) and VCCIO (2.5 V or 3.3 V) rails are decoupled with bulk and ceramic capacitors placed adjacent to each supply pin group. The BGA package requires careful PCB layout for fanout - typically a 4- or 6-layer stack-up with microvia or via-in-pad technology is recommended to escape the 1.0 mm pitch ball array reliably. Quartus II Web Edition or MAX+PLUS II software supports design entry and programming of this legacy MAX 3000A device.

主な用途
EPM3512AFC256-18 の用途: 7 件s: Legacy Industrial Control Glue Logic, PCI/ISA Bus Address Decoding, Multi-Rail Power Supply Sequencer, Reset Distribution and Watchdog Controller, Legacy Peripheral Register Bank, Bus Width Translation and Interfacing, State Machine and Protocol Encoder.
Legacy Industrial Control Glue Logic
The EPM3512AFC256-18 fits legacy industrial control designs where the original Altera MAX 3000A bill-of-material must be preserved across board revisions or field replacements. With 512 macrocells and 16 LABs it can absorb the wide-address decoding, bus arbitration, and interrupt-control glue logic that previously required four to six 22V10 PALs. The 18 ns tPD1 is more than adequate for 8/16-bit ISA bus timing, and the non-volatile EEPROM gives instant-on deterministic logic state at cold start - critical for fail-safe industrial controllers. Use this part only when re-validation cost of migrating to MAX II exceeds the BOM savings.
おすすめ
PCI/ISA Bus Address Decoding
The EPM3512AFC256-18 is well-suited to PCI/ISA peripheral cards that need wide address decoding and command-signal generation in a single non-volatile device. The 212 available user I/O pins handle ISA bus address (SA0-SA23), command (MEMR/MEMW/IOR/IOW), and chip-select fan-out without external bus-driver buffers. The 18 ns tPD1 fits the ISA bus 8 MHz timing with adequate margin, while the JTAG ISP allows board-level programming before connector assembly. The device replaces 4-6 discrete 22V10 PALs and reduces board area significantly.
おすすめ
Multi-Rail Power Supply Sequencer
The EPM3512AFC256-18 is ideal as a multi-rail power supply sequencer in ATCA/uTCA carrier boards, network switches, and telecom line cards that require deterministic turn-on and turn-off of 3.3 V, 2.5 V, 1.8 V, and 1.2 V rails. Its 512 macrocells can implement long state machines, fault-watchdog timers, and PG (power-good) cascaded sequencing in a single device. The EEPROM non-volatile configuration ensures the sequencer starts in a known state at cold power-up without waiting for boot memory, which is critical for ASIC reset distribution. Each VCCIO bank can drive PG signals at 2.5 V or 3.3 V levels to downstream rails.
おすすめ
Reset Distribution and Watchdog Controller
Use the EPM3512AFC256-18 as a centralized reset-distribution and watchdog controller for systems with multiple ASICs, FPGAs, or processors that require individual reset timing. The device's 16 LABs and 512 macrocells can host multiple independent watchdog timers, a master arbiter, and reset-pulse-stretching logic. The non-volatile EEPROM behavior gives a deterministic reset state at cold power-up before any boot configuration runs, eliminating race conditions during system bring-up. The 18 ns propagation delay supports reset assertion within one 33 MHz clock cycle.
おすすめ
Legacy Peripheral Register Bank
The EPM3512AFC256-18 can replace 8 to 12 discrete 74-series register/latch ICs that previously populated a peripheral card's I/O register bank. Each macrocell provides a D/T/JK/SR flip-flop with individually programmable clock and reset, and the 212 available user I/O pins comfortably handle 16-bit-wide data registers, control registers, and status registers. The MAX 3000A architecture delivers glitch-free register updates thanks to its synchronous product-term clocking, and the EEPROM-based instant-on means all registers initialize to a known default state at cold start.
おすすめ
Bus Width Translation and Interfacing
The EPM3512AFC256-18 functions as a flexible bus-width translator between 8-bit, 16-bit, and 32-bit processors or peripherals where commercial off-the-shelf translator ICs are unavailable or oversized. Each VCCIO bank can be powered at 2.5 V or 3.3 V independently, allowing the device to bridge a 3.3 V processor to a 2.5 V peripheral with no external level shifters. The 512 macrocells implement byte-enable logic, parity generation, and bus-snooping functions in a single chip, replacing two to four discrete 74-series bridge ICs and saving substantial board area in mixed-voltage designs.
おすすめ
State Machine and Protocol Encoder
The EPM3512AFC256-18 is a natural fit for complex state-machine controllers and protocol encoders where many state variables and timing windows must be tracked simultaneously. Its 512 macrocells accommodate large FSMs (50-100 states), and the four global clock networks allow independent timed state transitions across the design. Legacy protocol encoders - HDLC framing, I2C/SPI master controllers, parallel-to-serial converters - map efficiently onto the macrocell architecture. The EEPROM non-volatile storage lets the encoder start in a known protocol state at cold power-up without external boot logic.

設計ノート
The 256-ball FineLine BGA at 1.0 mm pitch demands a 4- or 6-layer PCB stack-up with controlled-impedance routing and microvia or via-in-pad technology to escape the ball array reliably. Place at least one full GND plane directly under the device to provide a low-impedance return path for the 16 LABs and the high-frequency JTAG signals. Decoupling: a 100 nF X7R ceramic placed within 2 mm of each VCCINT/VCCIO ball group, with a single 10 uF bulk tantalum or ceramic at the package edge. Estimated: typical MAX 3000A core current is around 200-400 mA at 3.3 V, so bulk capacitance must supply that during JTAG programming transients.
Route JTAG signals (TCK, TMS, TDI, TDO) as a daisy-chain or star from a single 4-pin header, with TCK having a series-termination resistor (33-68 ohm) close to the driver. Keep JTAG traces away from clock and high-speed I/O to avoid programming failures during ISP. The MultiVolt VCCIO banks should be grouped by destination voltage - one bank per voltage rail - to minimize simultaneous-switching-noise coupling. Estimate: VCCIO bank current scales with the number of I/O pins and toggle rate; budget 10-20 mA per switching output at 3.3 V.
Do not assume the EPM3512AFC256-18 is 5 V tolerant on its I/O. The MAX 3000A datasheet specifies 5 V tolerance only when VCCIO = 3.3 V and an external pull-up is used; with VCCIO = 2.5 V the I/O are not 5 V tolerant. Also avoid the common mistake of assuming that all 256 balls are user I/O - approximately 30-40 are dedicated VCCINT, VCCIO, GND, JTAG, and configuration pins, leaving 212 user I/O. Finally, do not design assuming a Quartus II device support newer than v9.0 SP2: the MAX 3000A family is legacy and not supported in current Quartus Prime releases.
The 18 ns tPD1 device supports synchronous logic up to roughly 50 MHz internal state-machine clock. For designs above 25 MHz on output registers, add series damping resistors (22-33 ohm) on clock-distribution nets to control edge rates. Tie unused I/O pins to GND through 10 kohm resistors or to a defined logic level - per the MAX 3000A datasheet, unused pins default to input-high but can draw supply current if left floating on a bus. Estimate: floating-bus current draw is 1-5 uA per pin; with 30+ unused pins this can add 30-150 uA of quiescent current.
