AP0101CS HDR: Image Signal Processor (ISP)

System Interfaces

SPI_SDI

Input

Data in from SPI flash or EEPROM memory. When no SPI device is fitted, this signal is

used to determine whether the AP0101CS should auto-configure:

0: Do not auto-configure; two-wire interface will be used to configure the device (host-

config mode)

1: Auto-configure.

This signal has an internal pull-up resistor.

SPI_SDO

Output

Data out to SPI flash or EEPROM memory.

SPI_CS_BAR

Output

Chip select out to SPI flash or EEPROM memory.

FV_OUT

Output

Host frame valid output (synchronous to PIXCLK_OUT)

LV_OUT

Output

Host line valid output (synchronous to PIXCLK_OUT)

PIXCLK_OUT

Output

Host pixel clock output.

DOUT[15:0]

Output

Host pixel data output (synchronous to PIXCLK_OUT) DOUT[15:0].

Note 20-bit output (SMPTE) also uses GPIO[5:2].

GPIO [5:1]

I/O

General purpose digital I/O.

Note: 20-bit output (SMPTE) also uses GPIO[5:2]

TRST_BAR

Input

Must be tied to GND in normal operation.

EXT_CLK_OUT

Output

Clock to external sensor.

RESET_BAR_OUT

Output

Reset signal to external sensor.

M_SCLK

Output

Two-wire serial interface clock (Master).

M_SDATA

I/O

Two-wire serial interface clock (Master).

FV_IN

Input

Sensor frame valid input.

LV_IN

Input

Sensor line valid input.

PIXCLK_IN

Input

Sensor pixel clock input.

DIN[11:0]

Input

Sensor pixel data input DIN[11:0]

TRIGGER_OUT

Output

Trigger signal for external sensor.

VDDIO_S

Supply

Sensor I/O power supply.

GND

Supply

Ground for sensor IO, host IO, PLL, VDDIO_OTPM, and VDD.

VDD_REG

Supply

Input to on-chip 1.8V to 1.2V regulator.

LDO_OP

Output

Output from on-chip 1.8V to 1.2V regulator.

Note: The regulator on the AP0101CS must be used.

FB_SENSE

Input

On-chip regulator sense signal.

GND_REG

Supply

Ground for on-chip regulator

VDD_PLL

Supply

PLL supply.

VDD

Supply

Core supply.

VDDIO_OTPM

Supply

OTPM power supply.

VDDIO_H

Supply

Host I/O power supply.
