From the 1920 Czech writer Karel Chapak's earliest use of the term robot in his script "Rossam's Universal Robot ", the pursuit and perfection of robots has never stopped. In recent years, robots have evolved with the development of technologies such as wireless sensor networks. People's requirements for robots are no longer limited to people doing things, but can connect to the Internet of Things, interact with other devices and people, of course, the requirements for data feedback, intelligent judgment speed, robot size and other performance are also increasingly High, such as small mobile robots that can be used in environments such as smart homes. One of the cores of the internal architecture of the robot is the microcontroller (MCU). The types of MCUs vary widely, and the developers of the robots are constantly evaluating various new MCUs to find a more suitable one. Freescale's first 5 V Kinetis E-series microcontrollers based on the ARM Cortex-M0+ processor in August this year is a good choice. Kinetis E complements robot design The Kinetis E-series microcontrollers combine low-cost, high-performance, advanced electromagnetic compatibility (EMC) and electrostatic discharge (ESD) protection to meet industrial-grade reliability and temperature requirements. Among them, KE02 is an entry-level product of Kinetis E series, its voltage range is 2.7 V~5.5 V, flash write voltage range is 2.7 V~5.5 V, temperature range (environment) is –40 °C~+105 °C. In terms of performance, it features up to 20 MHz ARM Cortex-M0+ core, single-cycle 32-bit × 32-bit multiplier, single-cycle input/output access port, built-in up to 64 KB of Flash, 256 B of EEPROM and 4 KB RAM. There are three Flex Timer (FTM) modules in the Kinetis E Series MCUs: a 6-channel FTM with dead time insertion and fault detection, and two TPM (Timer PWM Module) with Freescale 8-bit microcontroller HCS08. The module is backward compatible with 2-channel FTM. Each channel can be configured for input capture, output compare, edge or center-aligned PWM mode. This feature is ideal for motor control, plus Freescale's FreeMaster, which is suitable for algorithm parameter determination. The Kinetis E Series Power Management Module (PMC) offers three power modes: Run, Standby, and Stop modes that operate with energy efficiency. Kinetis E also has a built-in watchdog and programmable CRC module with a 64-bit unique identification number (ID) per chip for added security. 32-bit MCUs have always been operating at low voltages. When used in robots, motor control or even in the home, they are often used because of the harsh electromagnetic environment. People can only choose to select 16-bit or even 8-bit microcontrollers. The powerful electromagnetic noise immunity of the Kinetis E-series MCUs eliminates this concern and makes it possible to “change the MCU†of systems running in noisy environments.
