EP1810JI-45 - 48-Macrocell UV PLD, 33.3 MHz, 68-pin JLCC | Altera
MPN: EP1810JI-45 ✗ Akhir HidupEP1810JI-45 Ringkasan
An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic IC that uses EPROM/EEPROM cells to retain its logic configuration. EPLDs belong to the broader PLD family (programmable logic device), which sits alongside FPGAs, CPLDs, and SPLDs in the programmable logic hierarchy. Unlike SRAM-based FPGAs, EPLDs retain their bitstream without external memory, simplifying board design and providing instant-on behavior.
Key features of the EP1810JI-45 include 48 macrocells for combinational and registered logic, 33.3 MHz fMAX, 50 ns tPD, J-bend surface-mount terminals, and an industrial temperature range of -40 °C to +85 °C. The architecture integrates a programmable AND/OR array with feedback paths, enabling efficient implementation of state machines, decoders, and glue logic.
The EP1810 series uses Altera's Classic EPLD architecture, which combines high-density macrocells with predictable timing that is independent of routing density. Each macrocell contains a programmable flip-flop and configurable output polarity, and the device is programmed via the Altera Master Programming Unit or compatible third-party programmers using the JEDEC fuse-map format.
Typical applications include industrial control glue logic, address decoding in 8086/68000 microprocessor systems, bus interface adapters, state-machine controllers, and legacy replacement of discrete 74LS TTL logic. The wide 5 V supply tolerance and TTL-compatible I/O simplify integration into existing 5 V designs that require deterministic timing.
When designing with the EP1810JI-45, note that it is a UV-erasable/OTP device - in-window ceramic parts require a UV eraser for reprogramming. Designers should also confirm programming algorithm support with current Altera (now Intel FPGA) tools, as the Classic EPLD family predates modern Quartus support. For new designs, the MAX series CPLDs are recommended successors.

Aplikasi Umum
EP1810JI-45 cocok untuk 6 aplikasis: Microprocessor Address Decoding, Industrial Control Glue Logic, Bus Interface Adapter Logic, Legacy TTL Logic Replacement, State Machine Controllers, Aerospace and Defense Avionics Interfaces.
Microprocessor Address Decoding
The EP1810JI-45 is well suited to address decoding in 8086, 68000, and similar 16-bit microprocessor systems. Its 48 macrocells can implement complex decode maps with chip-select outputs, while the 50 ns tPD provides comfortable margin against typical 8 MHz 8086 bus cycles (125 ns). With 48 I/O pins and 12 dedicated inputs, the device can decode multi-bank memory maps and generate multiple peripheral chip-selects in a single package, replacing several discrete 74LS138/74LS139 decoders. The TTL-compatible 5 V I/O interfaces directly to legacy microprocessor buses, and the deterministic tPD eliminates the timing variability found in PAL/GAL-based designs.

Industrial Control Glue Logic
The EP1810JI-45 excels in industrial control designs that require deterministic glue logic between microcontrollers, sensors, and actuators. Its industrial -40 °C to +85 °C temperature range and 5 V TTL I/O make it a drop-in for PLC backplanes, motor controller boards, and instrumentation front-ends. The 50 ns tPD is more than sufficient for sub-microsecond control loops, and the 48-macrocell capacity can implement state machines, encoder quadrature decoders, and watchdog timers in a single device. Designers appreciate the predictable timing - unlike SRAM FPGAs, the EP1810JI-45's tPD does not vary with routing density, simplifying worst-case timing analysis in safety-critical industrial equipment.
Direkomendasikan
Bus Interface Adapter Logic
The EP1810JI-45 is commonly used as a bus interface adapter between legacy ISA, VME, or proprietary backplane buses. With 48 I/O lines, it can bridge 8/16-bit data buses, generate wait-state timing, and implement bus arbitration handshakes. The 33.3 MHz maximum frequency easily handles ISA's 8.33 MHz bus and slower VME transactions, while the deterministic 50 ns tPD guarantees compliant setup/hold timing. The 5 V TTL I/O matches the bus voltage levels directly without level shifters. When designing bus adapters, allocate macrocells for state-machine-based protocol engines and use the device's feedback paths to implement multi-cycle handshake sequences.

Legacy TTL Logic Replacement
The EP1810JI-45 is widely deployed to consolidate discrete 74LS and 74ALS TTL glue logic into a single programmable device. A typical design may replace 5-15 TTL packages (74LS00, 74LS74, 74LS151, 74LS153, 74LS174, 74LS374, etc.) with one EP1810JI-45, reducing board area, power consumption, and inventory SKUs. The 48 macrocells provide ample capacity for these consolidations, and the predictable tPD simplifies timing closure. This is one of the highest-value applications for the EP1810JI-45 in maintenance of legacy industrial and aerospace systems where original TTL parts are increasingly hard to source at reasonable cost.
Direkomendasikan
State Machine Controllers
The EP1810JI-45 is ideal for FSM (finite state machine) implementations in protocol engines, sequencers, and control logic. Each macrocell contains a programmable flip-flop with configurable output polarity, making state register implementation straightforward. The deterministic 50 ns tPD guarantees state-transition timing regardless of state encoding complexity, a key advantage over SRAM-based FPGAs where tPD varies with placement. A single EP1810JI-45 can implement state machines with 8-32 states plus associated output decode, covering most protocol engines, sequencers, and encoder/decoder logic in industrial, automotive, and telecom applications.
Direkomendasikan
Aerospace and Defense Avionics Interfaces
The EP1810JI-45 and its /883B military-screened sibling EP1810GM883B are used in aerospace and defense applications including MIL-STD-1553 interface logic, ARINC 429 bus adapters, and avionics display controllers. The /883B processing provides -55 °C to +125 °C military temperature range plus extended reliability screening, suitable for flight-critical designs. The 48 macrocells can implement protocol encoding/decoding, bus monitoring, and discrete I/O expansion for legacy avionics. Designers value the deterministic timing - critical when validating to DO-254 design assurance levels - and the long-term data retention of EPROM technology compared to SRAM FPGAs which require continuous configuration.

Diferensiator Kunci
- J-leaded ceramic chip carrier (JLCC) for high-reliability industrial applications (vsEP1810JC-45)
- Industrial temperature grade (-40 °C to +85 °C) with deterministic 50 ns tPD (vsEP1810GM883B)
- Same JEDEC-standard 68-pin footprint as the entire EP1810 family (vsMAX II EPM240T100C5N)
Catatan Desain
The EP1810JI-45 is UV-erasable through a quartz window on the top of the ceramic JLCC package. If the window is covered with an opaque label or damaged, erasure will fail. For one-time programming (OTP), simply do not erase after programming - the EPROM cells retain the bitstream. Newer designs should not assume modern Quartus tool support: use MAX+PLUS II or compatible legacy tools only.
Estimated: At VCC = 5.5 V maximum, fMAX = 33.3 MHz, and 100% I/O toggling, the EP1810JI-45 dissipates approximately 0.6 W. With the 68-pin JLCC ceramic package and typical industrial airflow, junction temperature rise is approximately 25 °C above ambient. Within the -40 to +85 °C industrial range this is acceptable, but designers should still provide adequate ground pins (4 GND pins in this package) and keep ceramic packages away from high-temperature sources.
When laying out a 68-pin JLCC footprint for EP1810JI-45, follow JEDEC standard MS-018 with 1.27 mm (0.050 inch) lead pitch. Use a socket for prototyping (e.g., 68-pin PGA-to-PLCC adapter or Aries 68-pin JLCC socket) so that UV-erase and reprogramming cycles are possible without desoldering. Always place decoupling capacitors (0.1 µF ceramic in parallel with 10 µF tantalum) within 5 mm of each VCC pin to suppress switching noise on the 5 V supply.
Informasi Konformitas
EP1810JI-45 is a ceramic JLCC part with tin-lead (SnPb) terminal finish and is therefore NOT RoHS compliant by default. Some -45 variants may be available with lead-free finishes through special-order channels; verify with the specific distributor before sourcing. REACH compliance is unknown - ceramic JLCC packages typically do not contain REACH SVHCs above threshold, but the EPROM die materials should be verified. AEC-Q100 is not applicable as this is an industrial/aerospace programmable logic IC, not an automotive-grade part.
