XL9535

XINLUDA · I/O Expanders · TSSOP-24

XL9535 from XINLUDA, in a TSSOP-24. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 INT output Active-LOW open-drain interrupt output. Asserted when any input pin state differs from its corresponding Input Port register value. Requires an external pull-up resistor to Vcc; IOL = 3 mA at VOL = 0.4 V.
2 A1 input Hardware I2C slave-address select bit 1. Must be tied directly to Vcc or GND (never floating) and must not change while device is powered. Sets bit 2 of the 7-bit slave address (base 0x20).
3 A2 input Hardware I2C slave-address select bit 2. Must be tied directly to Vcc or GND (never floating). Sets bit 3 of the 7-bit slave address (base 0x20).
4 P00 bidirectional Port 0 bit 0. Push-pull GPIO, configured as input at power-on. Per-I/O limit 25 mA; VIH = 0.7xVcc, VIL = 0.3xVcc; IOL up to 25 mA, IOH up to -10 mA.
5 P01 bidirectional Port 0 bit 1. Push-pull GPIO, configured as input at power-on. Same drive limits as P00.
6 P02 bidirectional Port 0 bit 2. Push-pull GPIO, configured as input at power-on.
7 P03 bidirectional Port 0 bit 3. Push-pull GPIO, configured as input at power-on.
8 P04 bidirectional Port 0 bit 4. Push-pull GPIO, configured as input at power-on.
9 P05 bidirectional Port 0 bit 5. Push-pull GPIO, configured as input at power-on.
10 P06 bidirectional Port 0 bit 6. Push-pull GPIO, configured as input at power-on.
11 P07 bidirectional Port 0 bit 7. Push-pull GPIO, configured as input at power-on. Total sourced current on P07-P00 must be limited to 80 mA.
12 GND power_in Supply ground (0 V reference).
13 P10 bidirectional Port 1 bit 0. Push-pull GPIO, configured as input at power-on.
14 P11 bidirectional Port 1 bit 1. Push-pull GPIO, configured as input at power-on.
15 P12 bidirectional Port 1 bit 2. Push-pull GPIO, configured as input at power-on.
16 P13 bidirectional Port 1 bit 3. Push-pull GPIO, configured as input at power-on.
17 P14 bidirectional Port 1 bit 4. Push-pull GPIO, configured as input at power-on.
18 P15 bidirectional Port 1 bit 5. Push-pull GPIO, configured as input at power-on.
19 P16 bidirectional Port 1 bit 6. Push-pull GPIO, configured as input at power-on.
20 P17 bidirectional Port 1 bit 7. Push-pull GPIO, configured as input at power-on. Total sourced current on P17-P10 must be limited to 80 mA.
21 A0 input Hardware I2C slave-address select bit 0. Must be tied directly to Vcc or GND (never floating). Sets bit 1 of the 7-bit slave address (base 0x20, giving 0x20..0x27).
22 SCL input I2C-bus serial clock input. Requires external pull-up to Vcc. Supports standard-mode (100 kHz) and fast-mode (400 kHz); VIH = 0.7xVcc, VIL = 0.3xVcc, 5 V tolerant.
23 SDA bidirectional I2C-bus serial data line (open-drain). Requires external pull-up to Vcc. IOL >= 3 mA at VOL = 0.4 V; 5 V tolerant.
24 VCC power_in Positive supply voltage, 2.3 V to 5.5 V. Typical ICC = 135 uA (max 200 uA) at 5.5 V with fSCL = 100 kHz; standby current typ 0.25 uA.
