ML7456N
Sigfox Sub-GHz Microcontroller
■Overview
ML7456N is a Sigfox Sub-GHz Microcontroller, which integrates MCU and RF Transceiver in a single chip.
RF frequency corresponds to 315MHz - 920MHz. It applis to Sigfox, it is low consumption and implements long-range
wireless communication.
MCU equips with an 16-bit CPU nX-U16/100(A35 core) and integrated with program memory(Flash memory), data
memory(RAM), data Flash and rich peripheral functions such as the multiplier/divider, CRC generator, DMA controller, Clock
generator, Simplified RTC, Timer, General Purpose Ports, UART, Synchronous serial port, I2C bus interface unit(Master, Slave),
Buzzer, Voltage Level Supervisor(VLS), Successive approximation type A/D converter, D/A converter , Analog comparator,
Safety function(IEC60730/60335 Class B), and so on.
The CPU nX-U16/100 is capable of efficient instruction execution in 1-instruction 1-clock mode by pipeline architecture
parallel processing.
The built-in on-chip debug function enables debugging and programming the software. Also, ISP(In-System Programming)
function supports the Flash programming in production line.
