PM256KNIA
PM256K is a 256K Bit/32K Byte SPI interface non-volatile memory. The chip adopts advanced PMTJ STT-MRAM technology, supports single-line SI and SO independent interfaces, achieves up to 20MHz read and write transmission, and has no delay in writing. It has excellent reliability and more than 20 years of data retention time. PM256K is an ideal solution for MCU to expand external memory. At the same time, due to the characteristics of fast throughput, few pins and small size, it has gradually become the choice of applications such as embedded, network switches, automobiles and the Internet of Things.
SSP1840
SSP1840 is a built-in clock and calibration-free energy metering IC, suitable for single-phase multifunctional electricity meter, smart socket, smart home appliances, electric bicycle charging pile and other applications with better cost performance.
SSP1840 integrates 2 high-precision sigma-delta ADC to measure current and voltage simultaneously. Reference voltage, power management and other analog circuit modules, and processing active power, current and voltage RMS electrical parameters digital signal processing circuit.
SSP1840 can measure electric parameters such as current and voltage RMS, active power, active energy, fast current RMS (for leakage detection/over-current protection), and temperature detection, waveform output and so on. SSP1840 output data through the UART/SPI interface. It is available for the smart socket, smart appliances, single-phase multi-function power meter, electric bicycle charging pile and information requirement of data acquisition in electricity applications.
SSP1840 has a patented anti-creep design, which can be combined with reasonable external hardware design to ensure that the noise energy cannot be calculated in the energy pulse when there is no load.
SSP8011
The SSP8011 is a low-power single-key touch sensor IC. The operating mode is divided into Normal mode and Low Power mode. Button mode or Switching mode output can be choosed, and the output level mode is optional.
SSP721A
SSP721A is a single chip transceiver developed for Meter-Bus standard (EN1434-3、EN13757) applications.
The SSP721A interface circuit adjusts the different potentials between a slave system and the Meter-Bus master. The connection to the bus is polarity independent and supports full galvanic slave isolation with optocouplers. The circuit is supplied by the master via the bus. Therefore, this circuit offers no additional load for the slave battery. A power-fail function is integrated. The receiver has dynamic level recognition, and the transmitter has a programmable current sink. A 3.3V voltage regulator, with power reserve for a delayed switch off at bus fault, is integrated.
SSP97950
SSP97950 is a general LCD driver IC with 8COMx35SEG total output capacity of 280 bits, suitable for commonly used character/graphic LCD screens. SSP97950 support serial data interface(I2C).
