The K40MCS6 is a microcontroller unit (MCU) with the following main functions:
Power management
It has 10 low-power modes with power and clock gating, enabling optimal peripheral activity and recovery times. It has a stop current of less than 1.45 µA and a run current of less than 277 µA/MHz, and can wake up from stop mode in 4 µs. It also supports full memory and analog operation down to 1.71 V for extended battery life.
Memory
It is equipped with 64 – 256 KB of flash memory that features fast access and high reliability, protected by 4-level security. Additionally, it has 2 KB of user-segmentable byte write/erase EEPROM for data tables and system data, with over 10 million cycles and a flash erase and write time of 70 µs. There is also 32 KB of flexible non-volatile memory (Flex NVM) for extra program code, data, or EEPROM backup.
Analog peripherals
It has up to two high-speed 16-bit analog-to-digital converters (ADCs) with configurable resolution, which can operate in single or differential output mode for improved noise rejection, achieving a conversion time of 500 ns with programmable delay block triggering. It also provides an analog voltage reference for analog blocks, ADCs, and digital-to-analog converters (DACs), reducing system cost.
Communication interfaces
It supports USB 2.0 On-The-Go (full speed) with device charge detect to optimize charging current and time for portable USB devices, and has a low-voltage regulator that supplies up to 120 mA off-chip at 3.3 V from a 5 V input. It also has up to 5 UARTs with IrDA support, including one UART with ISO7816 smart card support, and supports various data sizes, formats, and transmission/reception settings for multiple industrial communication protocols.
