NTM88H145S Datasheet | NXP Semiconductors

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 described in this data sheet, NTM88Hxx5S, provide low transmitting power consumption, large customer memory size, and single- or 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 2channel timer / pulse-width module. 2 Features and benefits - Optional pressure ranges1 - Optional accelerometer ranges: See Section 3. - Transducer measurement interfaces with low-power AFE: - 10-bit pensated pressure sense element - 10-bit pensated accelerometers - 8-bit pensated internal device temperature measurement - 8-bit pensated internal device voltage measurement - Two I/O pins can be used for external signals - 8-bit S08 pact instruction set controller: - 64 bytes low-power “always on“ NVM parameter registers - 512 bytes SRAM - 16 k B flash memory (512 bytes reserved for NXP coefficients) - Family of NXP firmware libraries available via royalty-free license - Programmable RF transmitter - Characterized for RF carrier typical of 315 MHz or 434 MHz - Characterized for FSK in ~3 k Hz increments or OOK modulation - Characterized for baud rate examples of 9.6 kbp/s, 19.2 kbp/s, and 38.4 kbp/s - Flexible 125 k Hz LF receiver: - Capability for ASK or OOK demodulation - Automated Manchester decoding - Two channel timer / pulse-width module - Client SPI to support host access to internal peripherals, registers, and memory - Seven GPIOs with programmable multiplexing to support software development, external analog voltage input, timer, SPI, and wake-up - Qualified in pliance with AEC-Q100, Rev.
