NTM88H065S
Overview
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.
- Optional pressure ranges1
- Optional accelerometer ranges: See Section 3.
- Transducer measurement interfaces with low-power AFE: - 10-bit compensated pressure sense element - 10-bit compensated accelerometers - 8-bit compensated internal device temperature measurement - 8-bit compensated internal device voltage measurement - Two I/O pins can be used for external signals
- 8-bit S08 compact instruction set controller: - 64 bytes low-power “always on“ NVM parameter registers - 512 bytes SRAM - 16 kB 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 kHz 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 kHz 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 compliance w
