CYPD2119-24LQXI

Cypress Semicon · CYPRESS · TQFN-24-EP(4x4)

CYPD2119-24LQXI from Cypress Semicon, in a TQFN-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 CC2 bidirectional USB PD connector detect/Configuration Channel 2 on the Type-C port.
2 CC1 bidirectional USB PD connector detect/Configuration Channel 1 on the Type-C port.
3 RD1 passive Dedicated Rd resistor pin for CC1; must be left open for cable applications and connected together with CC1 for UFP or DFP with dead battery applications.
4 VCONN2 power_in VCONN 2 input, 4.0 V to 5.5 V.
5 VCONN1 power_in VCONN 1 input, 4.0 V to 5.5 V.
6 VDDD power_in VDDD supply input/output, 2.7 V to 5.5 V.
7 VCCD power_out 1.8-V regulator output for filter capacitor; must be bypassed to ground with 1 to 1.6 µF X5R ceramic or better.
8 VDDIO power_in 1.71-V to 5.5-V supply for I/Os.
9 VDDD power_in VDDD supply input/output, 2.7 V to 5.5 V.
10 GPIO bidirectional General-purpose I/O; I/O pins are forced to the disable state during power-on and reset.
11 SWD_IO bidirectional SWD IO / GPIO / UART_1_CTS / SPI_1_MOSI.
12 SWD_CLK input SWD clock / GPIO.
13 GPIO bidirectional General-purpose I/O; GPIO 13 is I2C_1_SDA / SPI_1_MISO / UART_1_RX.
14 GPIO bidirectional General-purpose I/O.
15 GPIO bidirectional GPIO 15 is SPI_1_SEL / UART_1_RTS.
16 XRES input Reset input.
17 GPIO bidirectional General-purpose I/O.
18 GPIO bidirectional GPIO 18 is SPI_0_MOSI / UART_0_TX.
19 I2C_0_SDA bidirectional GPIO / I2C_0_SDA / SPI_0_SEL / UART_0_CTS; I2C pins from SCB 0 are overvoltage-tolerant and implemented as open-drain.
20 I2C_0_SCL bidirectional GPIO / I2C_0_SCL / SPI_0_MISO / UART_0_RTS; I2C pins from SCB 0 are overvoltage-tolerant and implemented as open-drain.
21 GPIO bidirectional General-purpose I/O.
22 GPIO bidirectional GPIO / SPI_0_CLK / UART_0_RX.
23 GPIO bidirectional General-purpose I/O.
24 GPIO bidirectional General-purpose I/O.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
