EPM9400RC240-20 Ringkasan

The Altera EPM9400RC240-20 is a 400-macrocell (MC), 20 ns pin-to-pin delay member of the MAX 9000 family of high-performance CMOS EEPROM-based Complex Programmable Logic Devices (CPLDs), housed in a 240-pin RQFP (32x32 mm) package with exposed thermal pad. It operates from a single 4.75 V to 5.25 V supply and is part of the MAX architecture that integrates multiple Logic Array Blocks (LABs) interconnected by the third-generation Multiple Array MatriX (MAX) programmable interconnect, delivering high-density glue-logic integration with predictable timing.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the deterministic timing of PAL/PLA architecture with the integration scale of a small FPGA, making it ideal for address decoding, bus interface, state-machine, and control-logic functions. Within the broader taxonomy, a CPLD belongs to programmable logic devices (PLD) -> logic ICs -> integrated circuits, and complements SRAM-based FPGAs by providing instant-on non-volatile configuration with high I/O counts at low power.

Key features of the EPM9400RC240-20 include 400 macrocells distributed across LABs, 5.0-V in-system programmability (ISP) via a built-in IEEE Std. 1149.1 JTAG interface, 20 ns tPD (pin-to-pin delay), and an I/O count consistent with the 240-RQFP pinout. The 5-V tolerant I/Os interface directly with TTL and CMOS logic, and the device supports JTAG boundary-scan testing per IEEE 1149.1 for board-level testability. Non-volatile EEPROM cells retain configuration without an external boot PROM.

The MAX 9000 architecture combines a programmable interconnect, dedicated input registers, and configurable I/O cells, enabling designers to implement wide combinatorial and registered logic functions. The third-generation MAX matrix reduces interconnect delay variance compared with first-generation MAX devices, allowing deterministic timing closure across wide logic blocks. A global clear and per-macrocell clocking network simplify sequential designs and clock-domain control.

Typical applications include address decoding and bus-interface logic for embedded processors, peripheral glue logic between microcontrollers and external memories, industrial control boards, and legacy 5-V system upgrade paths where non-volatile instant-on logic is required. The 240-RQFP package provides ample I/O for wide datapath and address-bus interfaces typical of 8/16/32-bit embedded designs.

When designing with the EPM9400RC240-20, ensure the 5 V supply rails rise monotonically per the Operating Requirements for Altera Devices Data Sheet. Inputs may undershoot to -2.0 V or overshoot to 7.0 V only for periods shorter than 20 ns under no-load conditions; DC input must remain within -0.5 V on I/O pins and -0.3 V on the four dedicated input pins. A JTAG chain must observe TCK/TMS/TDO/TDI ordering if multiple 1149.1 devices are present.

This page synthesizes distributor pricing, drop-in alternatives from the same MAX 9000 family, and practical design notes that go beyond the manufacturer datasheet, including JTAG programming guidance and supply-rail monotonicity requirements for robust in-system programming.

What is the difference between EPM9400RC240-20 and EPM9400RC240-15?

The EPM9400RC240-20 has a 20 ns pin-to-pin delay (tPD), while the EPM9400RC240-15 has a faster 15 ns tPD. Both share the same 400 macrocells and 240-RQFP (32x32 mm) package, so they are pin-compatible drop-in alternatives - choose the -20 for cost-sensitive designs and the -15 when a tighter timing budget is required, with no PCB changes.

Can EPM9400RC240-15 replace EPM9400RC240-20 directly?

Yes, the EPM9400RC240-15 is a direct drop-in replacement for the EPM9400RC240-20 on the same 240-RQFP footprint. Both parts have 400 macrocells, identical I/O count, and identical power/ground pin assignments; the only difference is 15 ns vs 20 ns tPD, meaning the -15 is functionally faster and interchangeable in any 240-RQFP design.

What is the best drop-in replacement for EPM9400RC240-20?

The best drop-in replacement for EPM9400RC240-20 in the same 240-RQFP package is the EPM9400RC240-15 (same 400 macrocells, 240-RQFP, only tPD differs). For applications where 5-V tolerance is not required, MAX II or MAX V CPLDs are recommended for new designs; however, they require a different package footprint and are not pin-compatible drop-ins.

EPM9400RC240-20 vs EPM9320RI208-20 - which is better for my design?

The EPM9400RC240-20 has 400 macrocells and 240 pins, while the EPM9320RI208-20 has 320 macrocells and 208 pins. Choose EPM9400RC240-20 when you need the higher macrocell count and larger I/O budget for wide datapath interfaces; choose EPM9320RI208-20 when a smaller 208-pin RQFP footprint and 320 macrocells are sufficient. Both are MAX 9000 family, 5 V, JTAG-ISP parts.

What is the difference between MAX 9000 and MAX II CPLDs?

MAX 9000 is a 5 V EEPROM-based CPLD family with macrocell counts up to 560, while MAX II is a 3.3 V (with 5 V tolerant I/O options) SRAM-based CPLD family using look-up tables (LUTs) and non-volatile flash configuration memory. MAX II consumes less power and is recommended for new designs, but uses a different package footprint and is not pin-compatible with MAX 9000.

How is the EPM9400RC240-20 programmed in-system?

The EPM9400RC240-20 is programmed in-system via the built-in IEEE Std. 1149.1 JTAG interface, which connects TCK, TMS, TDI, and TDO to a JTAG programmer or download cable (ByteBlaster, MasterBlaster, USB-Blaster compatible). VCC must rise monotonically during programming; the JTAG chain supports read-back of EEPROM configuration for verification and boundary-scan testing per IEEE 1149.1.

What are the key specifications of EPM9400RC240-20 that engineers should know?

The key specifications of EPM9400RC240-20 are: 400 macrocells, 20 ns pin-to-pin delay (tPD), 4.75 V to 5.25 V single supply, IEEE 1149.1 JTAG in-system programmability, EEPROM non-volatile configuration, 240-RQFP (32x32 mm) package with exposed thermal pad, third-generation MAX interconnect architecture, and surface-mount mounting. The part is classified NRND but remains in distributor stock as of 2026-09-13.

Panduan Pemilihan

Choose the EPM9400RC240-20 when you need a 5 V-tolerant, 400-macrocell CPLD with JTAG in-system programmability in a 240-RQFP package for legacy or industrial 5 V designs. Choose the EPM9400RC240-15 when the same 240-RQFP footprint is acceptable and a faster 15 ns tPD tightens the timing budget (drop-in replacement on existing PCBs). Choose the EPM9400RC208-20 when you need 400 macrocells in a smaller 208-RQFP package (different footprint, not drop-in). Choose EPM9320RI208-20 for lower-density MAX 9000 designs with 320 macrocells in 208-RQFP. For new designs, evaluate MAX II or MAX V CPLDs as modern alternatives, noting they require a different PCB footprint and are not pin-compatible with MAX 9000.

Catatan Desain

The EPM9400RC240-20 requires a single 5 V supply (4.75 V to 5.25 V). Per the Operating Requirements for Altera Devices Data Sheet, VCC must rise monotonically during power-up to ensure reliable ISP operation. Inputs may undershoot to -2.0 V or overshoot to 7.0 V only for periods shorter than 20 ns under no-load conditions. DC input levels must remain within -0.5 V on I/O pins and -0.3 V on the four dedicated input pins. Decoupling: place 0.1 uF ceramic capacitors close to every VCC/GND pair on the 240-RQFP package to suppress switching noise.

Route JTAG signals (TCK, TMS, TDI, TDO) as a clean daisy chain if multiple 1149.1 devices share the same JTAG bus. Keep JTAG traces short and isolated from switching signals; add 10 kohm pull-ups on TMS and TDI to prevent spurious test-mode entry. The exposed thermal pad on the 240-RQFP must be soldered to a ground plane for mechanical stability and thermal dissipation, even though the MAX 9000 family is CMOS-low-power.

Do not assume the EPM9400RC240-20 is still recommended for new designs - it is classified NRND by Altera/Intel. For new designs, evaluate MAX II or MAX V CPLDs, which offer lower power and modern features but require a different PCB footprint (not pin-compatible). Also, when migrating an existing design to the EPM9400RC240-15 (faster 15 ns tPD), verify the Quartus II/MAX+PLUS II timing simulation still meets all setup/hold requirements under worst-case conditions.
