I2130SYIR from Nuvoton Tech, in a SOP-14. 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 | MISO/GPIO2 | tri_state | SPI serial output from ISD2100 to host, high-impedance when SSB=1; configurable as GPIO2. |
| 2 | SCLK/GPIO1 | input | SPI serial clock input from host to ISD2100; configurable as GPIO1. |
| 3 | SSB | input | Active-low SPI slave select input from host with internal pull-up to VDD; when high, GPIO0/1/2 are automatically configured as MOSI/SCLK/MISO. |
| 4 | MOSI/GPIO0 | input | SPI serial data input from host to ISD2100; configurable as GPIO0. |
| 5 | VSSD | power_in | Digital ground. |
| 6 | VCCD_PWM | power_in | Digital power supply for the PWM driver. |
| 7 | SPK+ | output | Positive PWM driver output forming a differential pair with SPK- to drive an 8 ohm speaker or buzzer, high-impedance in power-down. |
| 8 | VSSD_PWM | power_in | Digital ground for the PWM driver. |
| 9 | SPK- | output | Negative PWM driver output forming a differential pair with SPK+ to drive an 8 ohm speaker or buzzer, high-impedance in power-down. |
| 10 | VCCD_PWM | power_in | Digital power supply for the PWM driver. |
| 11 | INTB/GPIO3 | output | Active-low interrupt request, open-drain output; configurable as GPIO3. |
| 12 | RDY/BSYB/GPIO4 | output | Reports SPI data transfer status, high means ISD2100 is ready for a new SPI command or data; configurable as GPIO4. |
| 13 | VCCD | power_in | Digital power supply (2.7V to 3.6V operating supply range). |
| 14 | GPIO5 | bidirectional | General-purpose I/O pin GPIO5. |
