STPMC1BTR

STMicroelectronics · Energy Metering · TSSOP-20

STPMC1BTR from STMicroelectronics, in a TSSOP-20. 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 MON output Programmable output pin: stepper node MB (charge pump) in standalone mode, or watchdog reset output in peripheral mode (APL = 0 or 1).
2 MOP output Programmable output pin: stepper node MA (charge pump) in standalone mode, or ZCR signal in peripheral mode.
3 SCS input Digital input that enables SPI communication when low; SPI transactions can be aborted by deactivating SCS, and in standalone mode a high level lets SYN, SCLNLC and SDATD output meter status.
4 VDD power_out 1.8 V output of the internal low drop regulator that supplies the digital core.
5 VSS power_in Ground level for the pad ring and power supply return.
6 VCC power_in Supply voltage; the application schematics show 3 V to 5.5 V, and the absolute maximum DC input voltage is -0.3 V to 6 V.
7 VOTP power_in Supply voltage for the OTP cells; the absolute maximum input voltage at the OTP pin is -0.3 V to 25 V, and the 14 V to 20 V programming voltage is generated from VCC for antifuse programming.
8 DAH input Input for non-multiplexed ΔΣ signals, used for the Hall sensor magnetic field information (fifth data input).
9 DAR input Input for multiplexed ΔΣ R-phase signals.
10 DAS input Input for multiplexed ΔΣ S-phase signals.
11 DAT input Input for multiplexed ΔΣ T-phase signals.
12 DAN input Input for multiplexed ΔΣ PTAT and neutral signals (neutral current or temperature sensing).
13 CLK output 2 mA clock output for the STPMSx devices.
14 VSSA power_in Ground level of the core.
15 SYN bidirectional Programmable input/output pin; when SCS is low it selects SPI read (SYN = 1) or write (SYN = 0) mode, and in standalone mode it can output the negative power indicator.
16 XTAL2 passive Crystal oscillator pin.
17 XTAL1 passive Crystal oscillator pin; digital signal timing is referenced to XTAL1, which may be a crystal or an external clock source.
18 SCLNLC bidirectional Programmable input/output pin; it is the SPI serial clock when SCS is low, and in standalone mode it is the no-load indicator output.
19 SDATD bidirectional Programmable input/output pin; it carries SPI serial data (input in write mode, output in read mode) and in standalone mode indicates the tamper condition.
20 LED output Programmable output pin: 3-phase energy pulsed output in standalone mode, or programmable energy pulsed output in peripheral mode.
