MPN: EPM3064ATI100-10N ✓ Hoạt độngEPM3064ATI100-10N Tóm tắt
What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that sits in the product hierarchy below FPGAs but above simple PAL/GAL devices. CPLDs combine an EEPROM (or flash) configuration memory, an AND/OR logic plane, and a wide macrocell fabric, giving deterministic timing, instant-on behavior (no external boot PROM required), and high-drive I/O suitable for bus interfacing, glue logic, and state-machine decoding. The MAX 3000A family is the 3.3-V extension of Altera's classic MAX architecture, succeeding the 5-V MAX 7000 family and targeting cost-sensitive industrial and consumer glue-logic applications.
Key features of the EPM3064ATI100-10N include in-system programmability via the built-in IEEE Std. 1149.1 JTAG interface, MultiVolt I/O supporting 2.5 V/3.3 V/5 V mixed-voltage interfacing, PCI-SIG compliance (Revision 2.2) at -4/-5/-6/-7/-10 speed grades, programmable power saving per macrocell, and a JTAG-based boundary-scan test interface. The EEPROM cells retain configuration for more than 20 years and are reprogrammable in-circuit, eliminating the need for an external boot PROM and supporting rapid prototyping and field upgrades.
Architecturally, the device consists of four Logic Array Blocks (LABs), each containing 16 macrocells, connected via a programmable interconnect array (PIA). The PIA routes up to 36 signals to each LAB, while each macrocell combines a programmable AND/OR array with a flip-flop and I/O control block. The JTAG port (TCK, TMS, TDI, TDO) supports ISP and complies with the IEEE 1149.1 boundary-scan standard for board-level test access.
Typical applications include bus and address decoding in industrial controllers, glue-logic integration on PC/104 and embedded SBC boards, state-machine and timer replacement, level translation between 3.3 V and 5 V domains, and PCI interface logic where deterministic -10 ns timing meets the PCI Local Bus Specification, Revision 2.2. The industrial operating range of -40 C to +85 C and in-system programmability make it well suited to factory-automation backplanes and telecom control cards.
A key design consideration is the JTAG chain topology: when multiple devices share TDI/TDO, ensure the JTAG chain order is consistent with the Quartus II / MAX+PLUS II programming file, and provision a TCK pull-down to avoid floating-clock states. For new designs, the MAX II family (e.g., EPM240T100) offers lower cost, lower power, and a 100-pin TQFP-compatible footprint migration path.

Ứng dụng tiêu biểu
EPM3064ATI100-10N phù hợp cho 6 Áp dụngs: Industrial Bus and Address Decoding, PCI Interface Glue Logic, Embedded SBC Glue Logic Replacement, 3.3 V to 5 V Level Translation Bridge, State-Machine and Timer Replacement, Prototyping and Field Upgrade via JTAG ISP.
Industrial Bus and Address Decoding
The EPM3064ATI100-10N is well matched to bus-address decoding in industrial controllers, where its 64 macrocells can implement 30+ chip-select decoders, address comparators, and wait-state generators in a single device. Its 10 ns pin-to-pin delay in the -10 speed grade keeps well within the ISA/PCI bus budgets, while MultiVolt I/O lets the CPLD sit between a 3.3 V microcontroller and legacy 5 V peripherals on the same backplane without level-shifters. JTAG ISP means field updates to decode maps can be done over the same test access port used for board bring-up.

PCI Interface Glue Logic
The EPM3064ATI100-10N is explicitly PCI-SIG Revision 2.2 compliant at -4/-5/-6/-7/-10 speed grades, making it suitable for implementing PCI target-state machines, configuration-space registers, and bus-arbitration glue on legacy add-in cards. The 66 user I/O cover the full 32-bit PCI bus plus side-band signals, while the deterministic 10 ns tPD in the -10 grade simplifies worst-case timing closure. MultiVolt I/O pads are 5 V tolerant, eliminating the need for external PCI clamp diodes when interfacing to 5 V mainboards.

Embedded SBC Glue Logic Replacement
PC/104, VME, and custom embedded SBC designs often need to consolidate discrete 74-series logic (74LS138/245/374, PAL/GAL glue) into a single low-power, reprogrammable device. The EPM3064ATI100-10N fits this role: 64 macrocells replace 4-6 discrete SSI/MSI packages, EEPROM retention means instant-on with no boot PROM, and the 100-pin TQFP provides ample I/O for 16- and 32-bit data buses plus address and control lines. Industrial -40 C to +85 C temperature range covers outdoor and factory-floor deployments.

3.3 V to 5 V Level Translation Bridge
The EPM3064ATI100-10N's MultiVolt I/O supports 2.5 V / 3.3 V / 5 V mixed-voltage signaling on a per-pin basis, making it a flexible bidirectional level shifter for legacy boards that need to add a modern 3.3 V ASIC or FPGA next to 5 V peripherals. With 66 I/O pins available, a single device can handle 16-32 channels of translation plus side-band control logic (bus turnaround, direction control). The 10 ns propagation delay in the -10 grade adds only one gate delay to the timing budget, which is acceptable for most peripheral buses.
Được đề xuất
State-Machine and Timer Replacement
Replacing discrete 74LS/HC state machines, one-shots, and counters with a single EPM3064ATI100-10N reduces PCB area and improves reliability on long-life industrial designs. The 64 macrocells, each with a dedicated flip-flop, comfortably implement 8-12 independent state machines with up to 16 states each, plus supporting counters and timers. Deterministic timing means no metastability surprises in safety-critical interlocks, and the EEPROM non-volatility keeps the design alive across power cycles without reconfiguration.
Được đề xuất
Prototyping and Field Upgrade via JTAG ISP
The built-in IEEE 1149.1 JTAG port on the EPM3064ATI100-10N enables in-system programming from a ByteBlasterMV or USB-Blaster cable without removing the device from the board - critical for prototypes and field-deployed equipment that needs occasional logic revisions. The same JTAG chain can be shared with other JTAG-compliant devices (microcontrollers, FPGAs, boundary-scan parts), and the Quartus II / MAX+PLUS II toolchains support incremental recompile-to-bitstream in under a minute for designs that fit in 64 macrocells.

Ghi chú thiết kế
Place the EPM3064ATI100-10N's 3.3 V VCCINT and 3.3 V/2.5 V/5 V VCCIO decoupling capacitors as close to each package pin pair as possible - one 0.1 uF X7R ceramic per VCC pin plus a single 10 uF bulk tantalum/ceramic at the board edge. The TQFP-100 package's exposed lead frame also benefits from a continuous ground plane on the layer directly beneath the IC, which both reduces ground bounce and improves thermal dissipation for hot-swap industrial backplanes.
The MultiVolt I/O pads are 5 V tolerant when VCCIO is set to 3.3 V, but they require careful series-resistor or source-termination design when driving long PCB traces. For clock outputs (e.g., TCK from the JTAG chain), keep the trace under 50 mm and add a 33 ohm series resistor at the driver to dampen reflections. Inputs from 5 V peripherals should be AC-coupled or diode-clamped if hot-plug events are possible.
When migrating from the EPM3064ATI100-10N to a MAX II device (e.g., EPM240T100C5N), do not assume JTAG chain order is preserved: MAX II uses a different BSDL file and TAP instruction set. Always re-validate the JTAG chain with the new BSDL and re-generate the Quartus Prime programming file before board bring-up. Also note that the MAX 3000A "N" suffix indicates lead-free processing while the absence of "N" indicates leaded finish - confirm before RoHS-critical designs.
Estimated: at the maximum I/O toggle rate of ~100 MHz on 32 of 66 outputs into 50 pF loads, the EPM3064ATI100-10N dissipates approximately 0.5-1.0 W. The TQFP-100 package's theta_JA of approximately 50 C/W (estimated, no datasheet figure available) yields a 25-50 C junction-temperature rise over ambient, well within the 125 C maximum junction spec. For sealed industrial enclosures with no airflow, derate toggle activity to 50% and consider a copper-pour heatsink on the top layer.
