EPM7032LC44-15 Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays on a single chip with a global interconnect fabric. CPLDs belong to the broader family of programmable logic devices, sitting alongside FPGAs in the digital IC hierarchy: programmable logic -> programmable logic device -> CPLD/FPGA -> logic IC -> integrated circuit. MAX 7000 devices use a second-generation MAX architecture with 5.0-V in-system programmability (ISP) through a built-in IEEE Std. 1149.1 JTAG interface, enabling designers to program, verify, and re-program the device on the board without removing it.
Key features of the EPM7032LC44-15 include 32 macrocells, 36 user I/O pins, 600 gates of logic capacity, 15 ns tPD (pin-to-pin delay), and a maximum internal operating frequency of 76.9 MHz. The device operates from a single 5.0 V supply (with VCCIO supporting 5.0 V or 3.3 V outputs) and is housed in a 44-pin PLCC package suitable for through-hole mounting and socket-based prototyping.
The MAX architecture uses a classic EEPROM-based non-volatile technology, providing instant-on behavior at power-up with no external configuration memory required. The 15 ns speed grade makes the LC44-15 suitable for control logic, address decoding, bus interfacing, and glue-logic integration where deterministic propagation delay and high I/O count are required. The PLCC-44 footprint is widely supported by low-cost sockets, simplifying field upgrades and legacy-system retrofits.
Typical applications include address decoding and bus interfacing in industrial control systems, glue-logic replacement in legacy 5V designs, I/O expansion for microcontrollers, and state-machine implementation in test & measurement equipment. Designers select the -15 speed grade when balancing timing margin against cost in non-critical control paths.
When designing with this device, ensure the VCC and VCCIO rails match the system logic levels. PLCC-44 sockets should be used for prototyping to allow easy device swap during development. Note that MAX 7000 devices have been classified by Altera/Intel as mature legacy products, so designers should verify long-term availability before new designs.

Applications typiques
EPM7032LC44-15 convient pour 6 applications: Address Decoding and Bus Interfacing, Legacy 5V Glue Logic Replacement, I/O Expansion for Microcontrollers, State Machine Implementation in Test Equipment, Industrial Control and Automation, Retrofit and Legacy System Maintenance.
Address Decoding and Bus Interfacing
The EPM7032LC44-15 is well suited to address decoding and bus interfacing in 5V industrial systems. With 32 macrocells and 36 user I/Os, the device can decode multi-bank memory maps and generate chip-select signals for peripheral clusters. Its 15 ns tPD pin-to-pin delay adds only one propagation stage between the address bus and the peripheral enable, leaving timing margin for downstream glue logic. PLCC-44 sockets make it easy to swap or reprogram during board bring-up.
Recommandé
Legacy 5V Glue Logic Replacement
The EPM7032LC44-15 is a classic drop-in replacement for discrete 74-series glue logic in legacy 5V systems. Its 5.0 V VCC and 5.0 V/3.3 V VCCIO support means it can replace multiple TTL/CMOS packages with a single programmable device, reducing board area and BOM cost. The 32-macrocell capacity handles typical decoder/mux/register tasks found in legacy backplanes, and the 15 ns tPD matches older bipolar logic speeds without introducing timing skew.
Recommandé
I/O Expansion for Microcontrollers
The EPM7032LC44-15 expands microcontroller I/O by offloading multi-pin tasks such as LED multiplexing, keypad scanning, or parallel peripheral control. With 36 user I/O pins, it can drive more outputs than most MCUs while offloading timing-sensitive bit-banging operations. The JTAG-based in-system programmability lets designers iterate on pin assignments during development, and the EEPROM-based non-volatile storage ensures instant-on behavior without firmware boot delays.
Recommandé
State Machine Implementation in Test Equipment
The EPM7032LC44-15 implements deterministic state machines for test and measurement equipment where predictable propagation delay matters. Its 15 ns tPD gives fixed worst-case timing independent of logic utilization, simplifying static timing analysis. The 600-gate capacity handles multi-state sequencers for relay control, signal-routing matrices, and handshake protocol converters, while the JTAG port enables in-system test vectors for production boundary-scan.
Recommandé
Industrial Control and Automation
The EPM7032LC44-15 is widely deployed in industrial PLCs, motor controllers, and process automation racks where its 5V operation, deterministic timing, and rugged PLCC-44 footprint suit long-life installations. The 32-macrocell capacity handles encoder quadrature decoding, PWM conditioning, and emergency-stop interlock logic. Last-time-buy status means existing installations must qualify second-source parts while new designs should consider MAX II or MAX V alternatives.
Recommandé
Retrofit and Legacy System Maintenance
The EPM7032LC44-15's PLCC-44 package and socket compatibility make it ideal for retrofitting legacy systems where the original CPLD has failed or been obsoleted. The 15 ns tPD matches the timing characteristics of most late-1990s/early-2000s designs, eliminating the need for firmware or PCB changes. Because the part is last-time-buy, retrofit projects should secure inventory immediately or migrate to a pin-compatible EPM7064LC44-15 for higher density.

Notes de conception
The EPM7032LC44-15 requires a clean 5.0 V supply on VCC and either 5.0 V or 3.3 V on VCCIO. Decouple VCC with a 0.1 uF ceramic capacitor placed within 5 mm of the VCC pin, plus a 10 uF bulk tantalum or ceramic capacitor. VCCIO must be tied to the same supply rail that the I/O signals interface with - mixing 5V VCC with 3.3V VCCIO is supported and used for level-shifting interfaces.
For prototypes, mount the PLCC-44 device in a low-profile through-hole socket (e.g. 3M Textool) so failed or wrong-programmed parts can be swapped without desoldering. Production boards may use SMT PLCC-44 footprints but should include a keep-out zone around the device to ease inspection and rework. JTAG signals TDI, TMS, TCK, TDO should be routed with short, parallel traces and a 10 kohm pull-up on TCK to prevent floating-clock noise during programming.
A common design pitfall is leaving JTAG pins TDI/TMS/TCK/TDO unconnected - while the device will operate, JTAG in-system programming becomes impossible without reworking the board. Always bring the JTAG pins to a 2x5 or 1x6 header for programming access. Another pitfall is using the EPM7032LC44-15 in designs that need active configuration at every power-on; while EEPROM-based MAX 7000 devices do provide instant-on behavior, ensure VCC ramp time meets the datasheet's monotonic-rise requirement to avoid partial configuration states.
The EPM7032LC44-15 in PLCC-44 has a thermal resistance (theta_JA) of approximately 45 C/W typical. Under normal 5V operation at moderate toggle rates, junction temperature rise is well within the 0-70C commercial range. However, in fully-loaded designs with all 36 I/Os switching at maximum frequency, the device may dissipate up to 0.5 W; in enclosed or high-temperature industrial environments, provide airflow or attach a small clip-on heatsink.
Informations de conformité
Legacy MAX 7000 device uses SnPb termination per Altera/Intel nomenclature - the base -15 part is non-RoHS. The -15N suffix denotes the lead-free RoHS-compliant variant. AEC-Q100 qualification is not applicable for this commercial-grade CPLD.
