EPM3128ATI100-5N - MAX 3000A CPLD, 128 Macrocells, TQFP-100 | Intel / Altera
MPN: EPM3128ATI100-5N ✓ Hoạt độngEPM3128ATI100-5N Tóm tắt
A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on digital IC that implements glue logic, bus arbitration, state machines, and interface bridging between microcontrollers, FPGAs, and ASICs. Within the programmable logic hierarchy, the MAX 3000A family sits below FPGAs (more logic, more delay, more power) but above discrete 74-series logic (more integration, lower BOM, easier re-spin). It uses a classic EE (EEPROM-based) architecture that retains configuration without external boot memory, giving it deterministic power-on behavior crucial for safety and control loops.
Key features include 128 macrocells organized in 8 Logic Array Blocks (LABs) of 16 macrocells each, a 100% interconnect matrix (PIA) with predictable timing, 5.0 ns combinatorial tPD, 80 mA DC drive per I/O with PCI-compatible drive strength, and JTAG boundary-scan support via IEEE 1149.1. Each macrocell contains a programmable AND/OR array plus a flip-flop that can be configured as D, T, JK, or SR, with per-macrocell product-term allocation up to 32 terms.
Typical applications include industrial control glue logic, address decoding in microcontroller-based systems, bus arbitration between CPU and peripheral buses, peripheral glue for legacy 5 V tolerant interfaces, and PCI/USB/ISA bridge functions. The wide I/O count (80 pins) makes it especially useful for replacing multiple discrete 74HC/74LVC packages in dense board designs.
When designing with the MAX 3000A, ensure the 3.3 V supply is well decoupled with 0.1 uF plus bulk capacitors placed near each VCC pin, and reserve a dedicated JTAG header (TCK, TMS, TDI, TDO, plus optional TRST) for in-system programming. The non-volatile EEPROM configuration eliminates boot time but requires a Quartus programmer for updates.

Ứng dụng tiêu biểu
EPM3128ATI100-5N phù hợp cho 7 Áp dụngs: Industrial Control Glue Logic, Microcontroller Bus Address Decoding, Peripheral Interface Bridging, Legacy 5V Interface Adaptation, State Machine and FSM Implementation, PCI Local Bus Arbiter, JTAG Chain Management and TAP Controller.
Industrial Control Glue Logic
The EPM3128ATI100-5N fits industrial control glue-logic designs because its industrial -40C to +85C temperature range tolerates factory-floor thermal stress while its 128 macrocells and 80 I/Os can replace 6-10 discrete 74HC/74LVC packages. The 5.0 ns pin-to-pin delay ensures deterministic timing for handshake and interrupt arbitration in PLC backplanes. The 5V-tolerant inputs interface directly with legacy 24V-to-5V opto-isolated signals, and non-volatile EEPROM configuration guarantees deterministic startup after power brownouts common in industrial mains environments.
Được đề xuất
Microcontroller Bus Address Decoding
The EPM3128ATI100-5N is ideal for microcontroller bus address decoding because its 128 macrocells can decode wide address buses (24-32 bits) with a single device, eliminating cascading 74HC138/74HC139 chips. The 5.0 ns tPD meets 8-bit/16-bit MCU cycle times at 50 MHz, and the 80 I/O pins accommodate chip-select, bank-select, and wait-state generation outputs. Non-volatile configuration means chip-selects are valid at power-on, eliminating boot glitches during MCU reset. Industrial temperature grade suits automotive and outdoor embedded controllers.
Được đề xuất
Peripheral Interface Bridging
The EPM3128ATI100-5N serves peripheral interface bridging applications well because it can simultaneously convert between parallel buses (ISA, PCI local bus), serial protocols (SPI, I2C, UART), and memory interfaces (SRAM, NOR flash) in one device. The 80 I/Os are sufficient for 16-bit data plus 24-bit address plus control signals for legacy bus bridging. 5V-tolerant inputs accept 5V peripheral signals, while 3.3V LVCMOS outputs drive modern MCUs. JTAG ISP enables firmware updates in deployed field equipment.
Được đề xuất
Legacy 5V Interface Adaptation
The EPM3128ATI100-5N adapts legacy 5V systems because its 5V-tolerant inputs accept 5.5V signals directly without external level shifters, while its 3.3V LVCMOS outputs drive modern 3.3V ASICs, FPGAs, and microcontrollers. Open-drain outputs with external pull-ups can also drive 5V CMOS inputs per the MAX 3000A datasheet. This makes it a one-chip translator between legacy 5V peripherals and modern 3.3V logic in industrial control retrofits.
Được đề xuất
State Machine and FSM Implementation
The EPM3128ATI100-5N implements complex state machines efficiently because each of its 128 macrocells contains a flip-flop configurable as D, T, JK, or SR with up to 32 product terms, ideal for FSM encoding. Multiple state machines can coexist in the same device, and the deterministic 5.0 ns tPD simplifies timing closure. Industrial temp grade and JTAG ISP make it suitable for deployed state-machine controllers in unmanned equipment where field re-programmability is required.
Được đề xuất
PCI Local Bus Arbiter
The EPM3128ATI100-5N works well as a PCI local bus arbiter because its 5.0 ns tPD meets PCI 33 MHz timing budgets for grant/req handshake, and the 80 I/Os handle multiple REQ/GNT pairs plus sideband signals. Non-volatile EEPROM configuration is critical for bus arbitration logic where power-on state must be deterministic. Industrial temp grade allows deployment in PCI-based industrial PCs operating in uncontrolled environments.
Được đề xuất
JTAG Chain Management and TAP Controller
The EPM3128ATI100-5N serves JTAG chain management because its native IEEE 1149.1 boundary-scan support lets it implement TAP controllers, JTAG multiplexers, and chain segmenters that switch JTAG access between multiple downstream devices. Industrial temp grade ensures reliable JTAG operation in test fixtures deployed on production lines. 5.0 ns timing meets TCK frequencies up to 200 MHz for high-speed programming.

Ghi chú thiết kế
The MAX 3000A CPLD requires both VCCINT (3.3V core) and VCCIO (3.3V I/O) supplies. Decouple each VCC pin with a 0.1uF ceramic capacitor placed within 5mm of the pin, plus a single 10uF bulk capacitor per device. Estimated: at 50 MHz toggle rate, typical Icc is approximately 50 mA; static Icc (no toggle) is below 10 mA. The POR circuit requires VCC to rise monotonically - if a brownout condition is possible, add a supervisor IC to reset the device.
Route the JTAG signals (TCK, TMS, TDI, TDO) as a single chain with stub-free traces. Keep TCK trace under 100mm and isolate it from switching signals with ground guard traces. Place a 10k pull-up on TCK and TMS to prevent floating JTAG state during power-up. Reserve a dedicated 2x5 or 2x7 header for the Altera ByteBlaster or USB-Blaster programming cable - do not share the JTAG pins with other functions.
The MAX 3000A has 5V-tolerant inputs but 3.3V outputs. When driving 5V-only inputs, use a discrete level shifter (e.g., 74HCT125 buffer) or configure the CPLD output as open-drain with a pull-up to 5V rail - the MAX 3000A datasheet permits open-drain output with external pull-up to 5.0V supply. Avoid capacitive loads above 50pF on high-speed outputs to prevent rise-time degradation.
Do not apply 5V to any VCCIO or VCCINT pin - only inputs are 5V-tolerant. Ensure the JTAG chain order matches the Quartus pin assignment file - reversing TDI/TDO prevents programming without damaging the device. When migrating between speed grades (-5, -7, -10), recompile the Quartus design for the new tPD to avoid hold-time violations. The 'N' suffix indicates lead-free / RoHS compliant packaging.
