Infineon Technologies SP300V5.0-E106-0

Overview

SP300V5.0-E106-0 from Infineon Technologies is a fully integrated tire pressure monitoring (TPM) sensor ASIC with embedded microcontroller, pressure (100–450 kPa), temperature (−40 to +125°C), supply voltage (2.1–3.6 V), and optional acceleration (−12 to 115 g) sensing. It features dual LF receivers for wake-up triggering, on-board EEPROM, GPIOs, and 11-bit pressure ADC - designed for direct mounting inside automotive wheel assemblies.

For engineers reviewing the SP300V5.0-E106-0 datasheet, SP300V5.0-E106-0 pinout, SP300V5.0-E106-0 application, or SP300V5.0-E106-0 equivalent, key selection criteria include its 100–450 kPa pressure range, dual-LF input capability, thermal shutdown at 102–123°C, sub-1 µA power-down current, and P-DSOSP-14-6 package compatibility with TPMS valve stem integration.

Technical Context

The SP300V5.0-E106-0 implements a mixed-signal ASIC architecture combining MEMS pressure transduction with a RISC-based microcontroller, dedicated 11-bit pressure/12-bit acceleration/10-bit temperature ADCs, and two independent ASK-demodulating LF receivers operating at 121.25–128.75 kHz. Its system clock runs at 1.8–2.2 MHz with ±20% LP oscillator tolerance.

It supports configurable interval timing (0.5/1.0/2.0/4.0 s), thermal shutdown with hysteresis (ϑSHTD = 102–123°C, ϑREL = 100–121°C), and low-voltage detection (Vmin = 2.0–2.2 V). Measurement data is conditioned internally and output via digital I/O, eliminating need for external signal chain components in standard TPM designs.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature before thermal shutdown activates?

The SP300V5.0-E106-0 triggers thermal shutdown between 102°C and 123°C (ϑSHTD), with master reset released between 100°C and 121°C (ϑREL). This hysteresis prevents oscillation near trip point and ensures stable recovery after cooling. The specification is validated across full voltage and process corners per AEC-Q100 stress testing.

Does SP300V5.0-E106-0 support both 125 kHz and 134.2 kHz LF frequencies?

No - SP300V5.0-E106-0 is specified only for 121.25–128.75 kHz carrier frequency with ASK modulation, aligned with global TPMS LF standards (e.g., SAE J2752). It does not support 134.2 kHz used in RFID or immobilizer systems; attempting operation outside its specified band results in failed wake-up detection.

Can the on-chip EEPROM be reprogrammed in-system after soldering?

Yes - the 2 Kbit EEPROM supports in-system programming via the TEST pin using Infineon's proprietary serial protocol. Field updates of calibration coefficients or unique IDs are possible without removing the device from the PCB, provided proper test pad access and voltage sequencing are maintained per Application Note AP32012.

Is acceleration sensing enabled by default in SP300V5.0-E106-0?

No - SP300V5.0-E106-0 corresponds to the "100–450 kPa" variant *with* acceleration sensor (per ordering code E106-0 vs E206-0 for no-acceleration version). However, the acceleration function must be explicitly enabled in firmware and consumes additional current (6–16 µAs per measurement); it remains inactive unless configured via register write.
