EPM7512BQC208-5 - MAX 7000B CPLD 512 Macro 176 IO | Altera
MPN: EPM7512BQC208-5 ✗ Akhir HidupEPM7512BQC208-5 Ringkasan
A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines multiple logic array blocks and macrocells with non-volatile configuration memory, allowing designers to implement glue logic, state machines, and bus interfaces without an external configuration device. In the logic IC hierarchy, a CPLD sits between simple PLDs (PAL/GAL) and FPGAs: CPLDs offer deterministic, single-cycle timing and instant-on operation, while FPGAs offer higher logic density. The MAX 7000B family is the 2.5 V evolution of the industry-standard MAX 7000 architecture.
Key features include 512 macrocells organized into 16 logic array blocks, 176 user I/O pins, a 163.9 MHz internal frequency (5 ns tPD), and EEPROM configuration that retains the design without power. The 2.5 V core reduces dynamic power versus 5 V MAX 7000S devices, and the device supports IEEE 1149.1 JTAG boundary-scan for in-system programming and board-level test.
The MAX 7000B architecture uses a programmable interconnect array (PIA) to route all logic signals, giving fully deterministic pin-to-pin delays independent of routing. Each macrocell provides a flip-flop with individual clock, clear, and preset, plus programmable output slew-rate and open-drain options. The 208-pin PQFP package provides 176 I/O with a 0.5 mm lead pitch.
Typical applications include PCI/ISA bus glue logic, DSP and microcontroller interface logic, memory controllers, and industrial control state machines. The 5 ns delay and 163.9 MHz operation suit address decoding and handshake logic where predictable timing matters more than raw gate count.
When designing with this device, note that the -5 speed grade is the fastest MAX 7000B grade and that the 2.5 V core requires level-compatible I/O planning for 3.3 V or 5 V peripherals.

Aplikasi Umum
EPM7512BQC208-5 cocok untuk 6 aplikasis: PCI/ISA Bus Glue Logic, DSP and Microcontroller Interface Logic, Industrial Control State Machines, Memory Controller and Address Decoding, Telecom and Networking Line Cards, Legacy Board Sustainment and Repair.
PCI/ISA Bus Glue Logic
The EPM7512BQC208-5 fits PCI and ISA bus glue logic because its 5 ns pin-to-pin delay and 163.9 MHz internal frequency provide deterministic, single-cycle address decoding and handshake generation without the routing-dependent timing of an FPGA. With 176 user I/O and 512 macrocells, it can absorb bus transceivers, wait-state generators, and chip-select decoders in one device. The EEPROM configuration means the logic is live within microseconds of power-up, satisfying PCI's requirement that configuration logic be ready before the host releases reset. A typical implementation places the CPLD between the host bridge and peripheral devices, decoding address and command lines and driving chip selects; the trade-off is that the 2.5 V core requires level-compatible I/O planning for 3.3 V or 5 V bus signals.
Direkomendasikan
DSP and Microcontroller Interface Logic
The EPM7512BQC208-5 is well suited to interfacing DSPs and microcontrollers to peripherals because its 512 macrocells can implement address decoding, wait-state generation, FIFO control, and interrupt aggregation while its 5 ns tPD keeps interface timing predictable. The 176 user I/O pins allow wide data and address buses to be routed directly, and the non-volatile EEPROM configuration removes the boot-time dependency that an SRAM-based FPGA would impose on the host processor. In a typical design the CPLD sits between a DSP's external memory interface and devices such as ADCs, DACs, or dual-port RAM, translating bus protocols and generating control strobes. The main trade-off is static power: the MAX 7000B architecture draws more quiescent current than modern MAX V or MAX 10 devices, which matters in always-on systems.
Direkomendasikan
Industrial Control State Machines
The EPM7512BQC208-5 suits industrial control state machines because its 512 macrocells and 16 logic array blocks can implement multiple concurrent state machines with deterministic 5 ns response, and its EEPROM configuration survives power cycling without a battery or boot PROM. In factory automation equipment, the CPLD typically sequences actuators, debounces sensor inputs, and enforces safety interlocks, where a missed or jittery transition can cause mechanical damage. The 176 I/O pins allow direct connection to opto-isolated inputs and relay drivers, and the 0C to 70C commercial temperature range is adequate for cabinet-mounted controllers. The trade-off is that the commercial grade is not rated for the -40C to +85C industrial range, so designs exposed to wide ambient swings should use an industrial-grade MAX 7000B variant instead.
Direkomendasikan
Memory Controller and Address Decoding
The EPM7512BQC208-5 is used for memory controller and address-decoding logic because its 5 ns propagation delay allows chip-select and RAS/CAS generation to meet tight DRAM and SRAM timing windows, while 512 macrocells can hold refresh counters, wait-state logic, and bank decoders simultaneously. The 176 user I/O pins accommodate wide address and data buses, and the EEPROM configuration ensures the controller is active immediately at power-up, before the processor begins its first memory fetch. In a typical board the CPLD decodes the processor address bus into bank selects and generates the memory control strobes, replacing several discrete 74-series devices. The trade-off is that the 2.5 V core limits direct interfacing to 5 V memory buses, so level shifters or series resistors may be required.
Direkomendasikan
Telecom and Networking Line Cards
The EPM7512BQC208-5 fits telecom and networking line cards because its 163.9 MHz internal frequency and 5 ns tPD support the handshake, framing, and backplane-interface logic used in T1/E1 and early Ethernet line cards, while 512 macrocells absorb glue logic that would otherwise require several discrete devices. The 176 user I/O pins allow direct connection to backplane connectors and PHY devices, and the non-volatile EEPROM configuration means the card's logic is ready immediately after hot-swap power-up, avoiding the configuration delay of an SRAM FPGA. In a typical design the CPLD implements the local bus interface, interrupt aggregation, and LED/status logic. The trade-off is that the MAX 7000B family is obsolete, so new line-card designs should migrate to an active CPLD or small FPGA family.
Direkomendasikan
Legacy Board Sustainment and Repair
The EPM7512BQC208-5 is widely used for legacy board sustainment because it is the original MAX 7000B device found on many 1990s and 2000s industrial, medical, and telecom boards, and replacement units must match the original 208-pin PQFP footprint and 2.5 V core exactly. When a board fails, the CPLD is often the only programmable device that cannot be substituted without a layout change, so sourcing genuine EPM7512BQC208-5 stock with valid date codes is critical. The EEPROM configuration also means a replacement device must be reprogrammed with the original JEDEC or POF file before installation. The trade-off is obsolescence risk: because the family is no longer produced, sustainment engineers should qualify the EPM7512BQC208-10 as a slower drop-in and stock both grades.

Diferensiator Kunci
- Fastest MAX 7000B speed grade (vsEPM7512BQC208-10)
- 208-pin PQFP footprint with 176 I/O (vsEPM7512BFC256-7)
- 2.5 V core for lower dynamic power (vsEPM7512AEQC208-7)
- Commercial temperature grade at lowest cost (vsEPM7512BFI256-7)
Catatan Desain
Decouple every VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus at least one 10 uF bulk capacitor per power plane region. The MAX 7000B core draws transient current during macrocell switching, and inadequate decoupling causes ground bounce that can corrupt EEPROM configuration during ISP. Estimated: at 163.9 MHz with 512 macrocells toggling, dynamic current can exceed 100 mA, so size the 2.5 V regulator for at least 300 mA with good transient response.
Route the JTAG signals (TCK, TMS, TDI, TDO) as short, controlled-impedance traces and keep TCK away from high-speed user I/O to avoid clock injection during in-system programming. Terminate TDO with a pull-up and TCK with a pull-down per the MAX 7000B programming guidelines. Place the JTAG header close to the device so the programming cable does not add excessive stub length, which can cause ISP failures on marginal setups.
Do not assume the EPM7512BQC208-5 is a drop-in for 5 V MAX 7000S designs: the 2.5 V core requires level-compatible I/O planning for 3.3 V or 5 V peripherals, and direct 5 V drive into I/O pins can exceed absolute maximum ratings. Also verify that the -5 speed grade timing is actually required; substituting the EPM7512BQC208-10 (10 ns) reduces cost and improves availability if the critical path has margin. Estimated: a 10 ns tPD adds 5 ns to each combinational path, which at 50 MHz consumes 25% of a 20 ns period.
