CSU8RP3215-SOP16

CHIPSEA · Microcontrollers (MCU/MPU/SOC) · SOP-16

CSU8RP3215-SOP16 from CHIPSEA, in a SOP-16. 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 VSS power_in Ground pin (地).
2 PT1.1/INT1/XIN/RI/TI bidirectional General-purpose I/O with open-drain output capability, external interrupt 1 input with wake-up function, external crystal input, UART receive and UART transmit (UART TX/RX selectable on PT1.1, PT1.2, PT3.3 or PT3.4 per the datasheet); PT1.1 can also serve as external RC clock input, depending on the XTAL_PIN code option.
3 PT1.2/INT1/XOUT/RI/TI bidirectional General-purpose I/O with external interrupt 1 input with wake-up function, external crystal output, UART receive and UART transmit.
4 PT1.3/INT1/RST/VPP input Input-only pin with external interrupt 1 input with wake-up function, reset input (external hardware reset is enabled by the RESET_PIN code option, active low, Schmitt trigger) and programming voltage VPP.
5 PT1.4/INT1/PWM2/BZ2/T4/PDA bidirectional General-purpose I/O with external interrupt 1 input with wake-up function, PWM2 output, buzzer 2 output, timer/counter 4 external input, and OTP programming data line (PDA).
6 PT1.5/INT1/PWM3/BZ3/PCL bidirectional General-purpose I/O with external interrupt 1 input with wake-up function, PWM3 output, buzzer 3 output, and OTP programming clock line (PCL).
7 PT1.6/INT1/PWM4/BZ4 bidirectional General-purpose I/O with external interrupt 1 input with wake-up function, PWM4 output and buzzer 4 output.
8 PT1.7/INT1 bidirectional General-purpose I/O with external interrupt 1 input with wake-up function.
9 PT3.6/AIN6/PWM4/PWM3H bidirectional General-purpose I/O with open-drain output capability (pull-down enabled by default), ADC input 6, PWM4 output and PWM3H output.
10 PT3.5/AIN5/PWM3/PWM3L bidirectional General-purpose I/O with open-drain output capability, ADC input 5, PWM3 output and PWM3L output.
11 PT3.4/AIN4/RI/TI bidirectional General-purpose I/O (pull-down enabled by default), ADC input 4, UART receive and UART transmit.
12 PT3.3/AIN3/CO/RI/TI bidirectional General-purpose I/O, ADC input 3, comparator output, UART receive and UART transmit.
13 PT3.2/AIN2/C0N/VREF bidirectional General-purpose I/O, ADC input 2, comparator negative input and ADC reference voltage input.
14 PT3.1/AIN1/C0P/INT1/T3 bidirectional General-purpose I/O, ADC input 1, comparator positive input, external interrupt 1 input with wake-up function, and timer/counter 3 external input.
15 PT3.0/AIN0/VREF/INT0/T2 bidirectional General-purpose I/O with selectable input logic level (VTHP30), ADC input 0, ADC reference voltage input / internal reference voltage output, external interrupt 0 input with wake-up function, and timer/counter 2 external input.
