ZSSC3224BI3R

RENESAS · Interface - Specialized · QFN-24-EP(4x4)

ZSSC3224BI3R from RENESAS, in a QFN-24-EP(4x4). 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 ZMDI-test unconnected Test pin reserved by the manufacturer; do not connect.
2 RES input Active-low ZSSC3224 reset with internal pull-up; a VDD-VSS-VDD transition at this pin causes a complete reset.
3 VDDB power_out Positive external bridge-sensor supply, internally generated with 1.60 V to 1.75 V (typ. 1.68 V) and bridge current limited to 1.8 mA to 16.5 mA for full PSRR.
4 INN input Negative sensor signal input (or sensor ground for absolute voltage-source sensors), with input voltage range 0.65 V to 1.05 V.
5 EOC output End-of-conversion or interrupt output, configurable via the INT_setup MTP setting.
6 MISO output Data output for the SPI interface (max. SPI clock 20 MHz; maximum 40 pF load on MISO at VDD = 1.8 V).
7 ZMDI-test unconnected Test pin reserved by the manufacturer; do not connect.
8 n.c. unconnected Not connected / not bonded; no connection required.
9 n.c. unconnected Not connected / not bonded; no connection required.
10 n.c. unconnected Not connected / not bonded; no connection required.
11 n.c. unconnected Not connected / not bonded; no connection required.
12 SCLK/SCL input Clock input for SPI (SCLK) or I2C (SCL) (I2C clock up to 3.4 MHz).
13 MOSI/SDA bidirectional Data input for SPI (MOSI) or data input/output for I2C (SDA).
14 VSSB power_in Negative external bridge-sensor supply, i.e. sensor ground; the datasheet lists this pin as OUT, it is mapped to power_in as a ground reference.
15 INP input Positive sensor signal input, with input voltage range 0.65 V to 1.05 V.
16 ZMDI-test unconnected Test pin reserved by the manufacturer; do not connect.
17 SS input Slave select for SPI; active low by default (polarity configurable via SS_polarity).
18 ZMDI-test unconnected Test pin reserved by the manufacturer; do not connect.
19 ZMDI-test unconnected Test pin reserved by the manufacturer; do not connect.
20 n.c. unconnected Not connected / not bonded; no connection required.
21 n.c. unconnected Not connected / not bonded; no connection required.
22 VDD power_in Positive supply voltage for the ZSSC3224, recommended range 1.68 V to 3.6 V (Table 3.1); absolute maximum -0.4 V to 3.63 V.
23 n.c. unconnected Not connected / not bonded; no connection required.
24 VSS power_in Ground reference voltage for the ZSSC3224; all voltages are referenced to VSS.
25 Exposed Pad unconnected Exposed thermal pad; do not connect electrically.
