EPC2T32N Visão geral

The Altera EPC2T32N is a 1.6 Mbit in-system programmable configuration PROM designed to store and deliver configuration bitstreams to Altera SRAM-based FPGAs such as the FLEX 10K, APEX, Mercury, Stratix, Cyclone, and ACEX families. The device is housed in a 32-pin TQFP (7x7 mm) package and supports serial configuration at up to 10 MHz clock rate, with dual voltage-supply support (3.0-3.6 V and 4.75-5.25 V) for FPGA interface flexibility.

What is a configuration PROM? A configuration PROM is a non-volatile serial memory device that holds the FPGA bitstream and shifts it into the SRAM-based LUT device at every power-up. Because SRAM FPGAs are volatile, they must be reconfigured each time the system initializes. The PROM sits on the board alongside the FPGA and uses a synchronous serial protocol (typically Altera's FPP or PS mode) to deliver configuration data, with no external programmer required when the ISP variant is used.

Key features of the EPC2T32N include 1.6 Mbit flash memory, in-system programmability via JTAG (IEEE 1149.1 boundary-scan), automatic CRC error detection during configuration, and open-drain CONF_DONE/nSTATUS signal pins for parallel multi-device chains. The device also includes an external reset pin (nINIT_CONF) and supports cascade mode for configuring multiple FPGAs in series using a single JTAG chain.

The architecture is built on a 0.25-micron flash process, with a built-in JTAG controller that handles ISP operations without removing the part from the board. The 4-pin serial interface (DCLK, DATA0, nCONFIG, nSTATUS) is fully compliant with Altera FPGAs in passive-serial configuration mode, and the dual-voltage interface allows the PROM side to run at 3.3 V while the FPGA side runs at 5 V, or vice versa.

Typical applications include Altera FPGA boot memory in industrial controllers, telecommunications line cards, prototyping boards, and embedded vision platforms. The 1.6 Mb density is sufficient for mid-sized FPGAs such as the Cyclone I/II, ACEX 1K, and APEX 20K families.

When designing with this device, ensure the JTAG chain order is preserved so the PROM and downstream FPGA can both be addressed individually. The 32-pin TQFP footprint is the industry-standard Altera configuration PROM land pattern, which allows board-level migration from the older EPC1 and EPC2LC20 devices to this part without PCB rework.

Where can I find the EPC2T32N pinout?

The EPC2T32N pinout is documented in the Altera configuration device datasheet, which lists all 32 TQFP pins including DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE, JTAG (TCK/TMS/TDI/TDO), VCCINT, and GND. The 32-TQFP (7x7 mm) pin numbering follows the JEDEC MS-026 standard with pin 1 at the top-left dot marker.

What is the operating voltage of the EPC2T32N?

The EPC2T32N operates from a dual supply of 3.0 V to 3.6 V (VCCINT3V3) and 4.75 V to 5.25 V (VCCINT5V) per the Altera configuration device datasheet. The dual supply is required because the PROM side may be powered at 3.3 V while the connected Altera FPGA runs at 5 V, or vice versa, providing level-shifting compatibility between mixed-voltage systems.

Guia de seleção

Choose EPC2T32N when you need a 32-TQFP RoHS-compliant 1.6 Mbit in-system programmable configuration PROM for Altera ACEX 1K, Cyclone I/II, or APEX 20K FPGA designs and want lead-free compliance. Choose EPC2T132N if you need to double the density to 3.2 Mbit for the same 32-TQFP footprint - it's pin-compatible and supports larger Stratix I/II bitstreams. Choose EPC2T32 only for legacy lead-bearing designs where RoHS compliance is not required (note: EPC2T32 is no longer recommended for new designs). Choose EPC1TI32 only when targeting small ACEX 1K / FLEX 10K devices whose bitstreams fit in 0.5 Mbit. Choose EPC1441TI32N if you need the built-in oscillator for self-clocked configuration without an external clock source. All five alternatives share the same 32-TQFP (7x7) package footprint, simplifying board-level migration.

Notas de projeto

The EPC2T32N's JTAG chain must include the PROM as the first device before the downstream Altera FPGA in the TAP scan order, otherwise Quartus II Programmer cannot address the PROM for ISP. Per the Altera configuration device datasheet, use a 10 kohm pull-up resistor on nCONFIG and CONF_DONE because these are open-drain outputs. Place 0.1 uF decoupling capacitors close to VCCINT3V3 (pin 6) and VCCINT5V (pin 15).

Do not confuse the EPC2T32N (32-TQFP, 1.6 Mbit) with the EPC2T132N (32-TQFP, 3.2 Mbit) or the EPC2LC20 (20-PLCC, 1.6 Mbit). All three share the same Altera configuration protocol but have different pinouts and densities. Always double-check the data code on the top mark versus the datasheet before soldering. The 'N' suffix indicates RoHS/lead-free finish.

Keep DCLK and DATA0 traces short and length-matched to avoid configuration timing violations. The Altera configuration device datasheet specifies DCLK rise/fall times under 20 ns for reliable sampling at 10 MHz. Series-terminate DCLK with 33 ohm if the trace exceeds 50 mm to prevent ringing on the 32-TQFP footprint.
