EPCQ16ASI8N

Intel/Altera · Programmable Logic Device (CPLDs/FPGAs) · SOIC-8

EPCQ16ASI8N from Intel/Altera, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 nCS input Active-low chip select that toggles at the beginning and end of a valid operation; when high the device is deselected and DATA[3:0] are tri-stated, and a falling edge is required after power up before any operation.
2 DATA1 bidirectional In AS x1 and x4 modes outputs serial data to the FPGA on falling DCLK edges during read or configuration, and acts as an input during quad input fast write bytes.
3 DATA2 bidirectional In AS x4 mode outputs serial data to the FPGA on falling DCLK edges during read or configuration operations; in AS x1 mode this pin must connect to VCC.
4 GND power_in Ground pin.
5 DATA0 bidirectional In AS x1 mode it is the data input for write or program, latched at rising DCLK edges; in AS x4 mode it is an I/O pin that inputs data during write and outputs data on falling DCLK edges during read or configuration.
6 DCLK input Serial clock provided by the FPGA; data on DATA[3:0] is latched into the device on rising DCLK edges and changes after the falling edge.
7 DATA3 bidirectional In AS x4 mode outputs serial data to the FPGA on falling DCLK edges during read or configuration operations; in AS x1 mode this pin must connect to VCC.
8 VCC power_in Connect the power pins to a 3.3-V power supply.
