Product overview
Description
The NTM88 family consists of small (4 mm x 4 mm x 1.98 mm), fully integrated tire pressure monitoring sensors (TPMS). The devices in NTM88Hxx5S provide low transmitting power consumption, large customer memory size, and dual-axis accelerometer architecture. The NTM88Hxx5S TPMS solution integrates an 8-bit microcontroller (MCU), pressure sensor, accelerometers in four ranges, programmable RF transmitter and flexible LF receiver. The sensor supports seven GPIOs, client SPI, and a 2-channel timer / pulse-width module.
