TheInfineon XC800 family is an8-bitmicrocontroller family, first introduced in 2005,[1] with a dual cycle optimized8051 "E-Warp"[2][3]core. The XC800 family is divided into two categories, the A-Family forAutomotive and the I-Family for Industrial and multi-market applications.
The Industrial-Family also called I-Family product series ranges from 2KB to 64KBflash memory and from 16- to 64-pin package options. It can be found in applications likemotor control ofeBikes,pumps andfans e.g. in air conditioners, as display ortouch button controls or in digital controlled power supplies e.g. for motor drives or lighting.
Automotive devices from the XC800 family can be found in safety and powertrain applications like motorcycle BCM, lighting, window lift, low end airbags, steering angle sensors, pumps, cooling fans and valve/throttle controls. All devices are compliant with the AEC Q100 standards for automotive electronics.
The instruction set consists of 45% one-byte, 41% two-byte and 14% three-byte instructions. Each instruction takes 1, 2 or 4machine cycles to execute. In case of access to slower memory, the access time may be extended by wait cycles (one wait cycle lasts one machine cycle, which is equivalent to two wait states). The XC800core supports a range of debugging features including basic stop/start, single-step execution, breakpoint support and read/write access to the data memory, program memory and special function registers. A 16-bit co-processor provides additional computing performance and is optimized for the processing of multiply / divide operations and for the execution of theCORDICalgorithm for trigonometric operations.
The 8-bit MCUs have an embedded user-programmable non-volatile flash memory that allows for fast and reliable storage of user code and data. It is operated with a single 2.5 V supply from the embeddedvoltage regulator (EVR) and does not require additional programming or erasing voltage. The sectorization of theflash memory allows each sector to be erased independently. A flash error correction(ECC) can detect double-bit errors and correct single-bit errors as well as protect against invalid code execution. Up to 3KB ofRAM is featured, part of this memory being XRAM.
Theanalog-to-digital converter module (ADC) uses the successive approximation method to convert analog input values (voltages) to discrete digital values with 10-bit resolution. One ADC kernel (ADC0) operates on a user-selectable number of input channels. The input channels can be selected and arbitrated flexibly.
The CCU6 is a capture and compare unit which generatesPWM signals over different duty cycles and multiple output channels. It operates with 16-bit timers clocked at 48 MHz and can trigger the ADC operation to harmonize control loops. The CCU6 provides application-specific modes, like for AC drive control or brushless DC-motors using Hall sensors or back-EMF detection. Furthermore, block commutation and control mechanisms for multi-phase machines are supported.
LEDTSCU is a functional unit for the control ofcapacitive touch pads and a matrix ofLEDs through the same pins. For example, 7 segment displays which are commonly used can be controlled by such a matrix. The principle of time-multiplexed operation of two or more functions, in this case touch control and LED-control, reduces the amount of pins used. The capacitive touch control is adjustable in sensitivity to fit for various cover materials and aROM library assists the application development.
XC800 features a set of interfaces for serial communication includingUART,SPI andI2C as well asCAN connectivity. CAN (Controller Area Network) is a robust serial bus designed for board to board communication in noisy environments such as automobile and industrial control systems. MultiCAN developed by Infineon improves upon previous CAN implementations by adding features such as additional CAN nodes, more message objects linked list management of message objects and support for TTCAN level 2.
Easy Kits and Starter Kits are microcontroller evaluation boards available for all XC800 devices. Application Kits are more application specific kits e.g. for motor control designs. They contain example codes for various control schemes, power boards or motor types and the according hardware.
