EP1K10TI100-2 Présentation
An FPGA (Field Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), embedded memory, and programmable interconnect that the designer can configure after manufacturing to implement any digital logic function. FPGAs sit hierarchically between fixed-function ASICs (Application Specific Integrated Circuits) and CPLDs (Complex Programmable Logic Devices), offering higher logic density and richer I/O features than CPLDs but lower performance-per-watt and higher unit cost than volume-production ASICs. The ACEX-1K family was Altera's first FPGA family to embed dedicated dual-port RAM (EAB) blocks alongside the logic fabric.
Key features of the EP1K10TI100-2 include 72 LABs (Logic Array Blocks) each containing 8 logic elements, 3 embedded array blocks (EABs) providing 12,288 total RAM bits, four low-skew global clock networks, multi-voltage I/O support (2.5 V core with 3.3 V / 5 V tolerant I/O on selected banks), and in-system programmability via the IEEE 1149.1 JTAG interface or the Altera EPC serial configuration device.
The device architecture combines an SRAM-based look-up table (LUT) logic fabric with fast carry chains for arithmetic, distributed inter-LAB routing, and dedicated phase-locked loops on higher-density ACEX-1K members (the EP1K10 is the smallest member and does not include PLLs). It targets glue-logic, bus-bridging, and state-machine consolidation designs where the 10K-gate capacity is sufficient.
Typical applications include industrial control interfaces, communications glue logic, legacy 8051/microcontroller bus expansion, I/O buffering and level translation, custom state machines, and low-volume prototyping where the design may later migrate to a structured ASIC.
When designing with this part, note that the 100-pin TQFP limits I/O count to 66 and the absence of on-chip PLLs constrains clock management; designers needing more I/O or clock synthesis should migrate to the EP1K30 / EP1K100 in TQFP-144 or larger packages. Power estimation requires Altera's PowerPlay tool because static and dynamic power depend heavily on utilization and toggle rate.

Applications typiques
EP1K10TI100-2 convient pour 6 applications: Industrial Control Glue Logic, Legacy Bus Bridging & Level Translation, Custom Peripheral State Machines, Prototype & Low-Volume Production Bridge to Structured ASIC, Communication Equipment Glue Logic, Legacy Repair & Maintenance Stock.
Industrial Control Glue Logic
The EP1K10TI100-2's 10K gate capacity, 66 user I/Os, and industrial -40 °C to +85 °C temperature range make it well suited to consolidate the scattered glue logic that typically surrounds an industrial controller — address decoding, bus arbitration, handshaking between heterogeneous peripherals, and small custom state machines. The 100-pin TQFP package is hand-solderable for prototype rework and accepts standard 0.5 mm-pitch PCB footprints compatible with leaded and lead-free reflow profiles.
Recommandé
Legacy Bus Bridging & Level Translation
With multi-voltage I/O support (3.3 V / 5 V tolerant banks), the EP1K10TI100-2 acts as a flexible bridge between older 5 V microcontrollers and modern 3.3 V peripherals, eliminating discrete translator ICs. Its 576 logic elements easily absorb typical 8-bit / 16-bit bus-multiplexing state machines, and the 66 I/Os leave margin for parity bits, chip selects, and interrupt aggregation. The SRAM configuration allows in-field firmware updates whenever the legacy bus protocol is extended or replaced.
Recommandé
Custom Peripheral State Machines
The ACEX-1K fast-carry chain enables efficient arithmetic and counter implementations, while the 12,288 RAM bits distributed across 3 EABs allow small FIFO and lookup-table memory buffers to be placed inside the FPGA. Combined with the 200 MHz internal toggle rate, the EP1K10TI100-2 builds protocol engines for I²C, SPI, UART, and custom bit-banged interfaces that would otherwise require a CPLD with limited density or a micro-controller with underwhelming real-time performance.
Recommandé
Prototype & Low-Volume Production Bridge to Structured ASIC
The EP1K10TI100-2 lets a designer validate hardware architecture and firmware in the same SRAM-reconfigurable fabric that can later be migrated to a HardCopy II structured ASIC for volume production. This FPGA-first methodology de-risks the architecture and yields a bitstream-compatible design, dramatically reducing NRE cost. The 100-pin TQFP footprint matches the HardCopy II prototype package, eliminating PCB re-spin when crossing from prototype to volume.
Recommandé
Communication Equipment Glue Logic
Telecom and networking equipment frequently uses small ACEX-1K devices for backplane management, LED-control scan matrices, hot-swap controller interfacing, and clock-domain crossing. The EP1K10TI100-2's 4 dedicated global clock networks and 66 I/Os are sufficient to fan out management data between line cards, while its 200 MHz internal performance comfortably handles 100 Mbps Ethernet MDIO and slow SPI management buses without timing closure issues in the -2 speed grade.
Recommandé
Legacy Repair & Maintenance Stock
Because the EP1K10TI100-2 is classified NRND by Altera/Intel but is still in distributor inventory as of 2026-09-07, it is the most cost-effective option for repairing fielded systems whose PCB was designed around the 100-pin TQFP footprint and the ACEX-1K JTAG programming chain. Holding a small buffer of these parts avoids board re-spin when an obsolete unit fails in service. The same JTAG tools (USB-Blaster, Quartus II 13.0) and bitstream files can be re-used without any firmware change.

Principaux différenciateurs
- Smallest ACEX-1K member in 100-pin TQFP (vs EP1K30TC144-2)

- Mature Altera toolchain support (vs Lattice ispMACH4K equivalent)
Notes de conception
Estimated: ACEX-1K FPGA core power at VCCINT=2.5 V depends on utilization and toggle rate. A typical EP1K10 design running at 50 MHz with 70% utilization and 20% average toggle rate draws approximately 60–90 mA from the 2.5 V rail (150–225 mW). Add at least 100 mV bulk decoupling (10 µF tantalum or polymer) plus 0.1 µF + 1 nF ceramic caps at every VCCINT pin. VCCIO banks must each be supplied separately; mixing 3.3 V and 5 V on the same bank is not allowed.
Estimated: the TQFP-100 package has a θJA of approximately 35–40 °C/W on a standard 2-layer JEDEC board and approximately 20–25 °C/W on a 4-layer board with adequate ground pour. At 225 mW typical dissipation, junction temperature rise is roughly 5 °C above ambient on a 4-layer board — well within the 125 °C junction rating. Industrial-temperature designs should still measure worst-case leakage after programming to confirm margin at 85 °C ambient.
Three pitfalls are common when bringing up the EP1K10TI100-2. (1) The configuration is volatile — every power-up reloads from an external EPC serial EPROM or via JTAG; missing or corrupted bitstream leaves all I/O tri-stated and CONF_DONE low. (2) MSEL0/MSEL1 pins must be hard-wired to the correct mode (00=JTAG, 01=AS serial, 10=AP, 11=PS) — a floating MSEL prevents configuration. (3) The nSTATUS and CONF_DONE pins are open-drain and require 10 kΩ pull-ups to VCCIO, otherwise configuration handshakes fail intermittently.
Route all four global clock nets (CLK0, CLK1, and the two internally-generated globals) using matched-length traces to minimize skew between registers. Place configuration EPROM (EPC2 or EPCS1) within 5 mm of the FPGA data and clock pins to avoid signal-integrity issues at high DCLK rates. All JTAG signals (TCK, TMS, TDI, TDO) must be pulled up/down per IEEE 1149.1 to keep the TAP controller in a defined state during board reset.
Informations de conformité
EP1K10TI100-2 is an Altera ACEX-1K family part originally released in the late 1990s; -2 speed grade industrial parts may be non-RoHS depending on date code, while -2N variants are explicitly lead-free. Compliance status not stated in the provided web data; mark as unknown and verify the manufacturer's date-code / lot information before shipping to RoHS-restricted markets.
