Infineon 8-/16-/32bit MCUs

Infineon Technologies AG has released new microcontrollers with embedded flash technology designed to meet the performance and reliability requirements industrial applications.

The new Infineon MCUs include the 8bit XC864 and XC886 HOT, the 16bit series XE162M, XE164M and XE167M, and the 32bit TC1167 and TC1197. The company has also received the VDE certification for the 8bit family XC800 which grants the functional safety requirements for home appliances under EN/IEC60335-1 Class B standard.

8-/16-/32bit families
The new XC864 series expand the Infineon XC800 MCU family to provide more scalable performance. Designed for cost-sensitive motor control applications, the XC864 series combines in a small footprint TSSOP-20 package a standard 8051 core with on-chip flash memory of up to 4Kbyte and powerful on-chip peripherals. The XC864 series also features an internal clock source and embedded voltage regulator, supporting single voltage supply of 3.3- or 5.0V. Its target applications include electric bikes, DC fans, stepper motors, and high-intensity discharge (HID) lighting as well as home appliances and power tools.

Infineon expands its product portfolio for demanding environments with ambient temperature up to 140C. The new XC886 HOT fulfills all requirements in respect to performance and quality at this high temperature. The MCU comes with 24- or 32Kbyte of flash memory, 10bit ADC with high accuracy and fast conversion time of less than 1.5?s, a 16bit vector computer supporting Field Oriented Control and a Capture/Compare Unit with two independent 16bit timers.

The XE162M, XE164M and XE167M MCUs are designed for use in a wide range of demanding real-time industrial drive applications, such as servo drives, HVAC compressors and blowers, pumps, advanced sensing and power supplies. The XE166M series provides additional advanced safety features for SIL3 applications and 64-pin devices (the XE162M series) with a small footprint. In addition, the XE166M series offers high CPU performance combined with enhanced I/O capabilities, flexible power management and peripherals. The highly configurable serial interface USIC supports multiple protocols, such as asynchronous and synchronous serial interfaces (ASC, SSC), I?C, LIN and communication to memory SD cards. The XE166M MCUs combine the enhanced C166S-V2 core with an extended set of peripherals and on-chip memory. All three devices in the XE166M series provide embedded plash; memory protection unit; ECC for SRAM and flash and a memory checker to ensure data integrity; a 80MHz CPU clock; a multiply and accumulate unit for DSP function; advanced interrupt-handling; fast high-resolution ADC capabilities; and an on-chip debug system for enhanced development.

Infineon has also expanded its AUDO Future family of 32bit MCU with two derivatives, TC1167 and TC1197, designed for use in demanding real time industrial applications, such as multi-axis controllers for up to five 3-phase complementary pulse-width modulators. They support multiple modulation strategies such as Space Vector Control or Direct Torque Control and provide multiprocessor support for reliability and safety.

The rich peripheral set includes a flexible timer unit (GPTA) for complex signal generation with digital signal filter functionality; fast multi-channel ADCs; MultiCAN module; ASC, SSC interfaces and a micro link interface for multicontroller communication. The flexible GPTA concept enables scalable motor control solutions and an autonomous full coherent high-speed PWM generation to achieve highly efficient drive operations.

Operating at 180MHz, the new high performance TC1197 is equipped with up to 4Mbye of embedded flash, a total of 224Kbyte RAM, 48 ADC channels and 2 GPTA units plus one local timer cell unit. This device provides 219 digital general purpose I/O lines and includes a 32bit external bus unit, e.g. for the connection to external memories, FPGAs or ASICs. For harsh environments, such as servo drive applications with high ambient temperatures, Infineon qualified the TC1197 for a temperature range of -40C to 125C.

In the mid-range portfolio, the new TC1167 which operates at 133MHz offers 1Mbyte of embedded flash, a total of 128Kbyte RAM, 32 ADC channels and 1 GPTA unit.

Support tools
Infineon offers free tool chains for its newest 8- and 16bit MCU families. The PK51 developments tools from the tool provider Keil are available for the XC800 family, and the Tasking C Compiler from Altium with EDE, simulator and debugger are available for the XE166 family. Several comprehensive tool chains from third parties are offered for embedded software design inclusive real-time OS. IEC61131-3 support for programmable logic controller is provided for the entire AUDO Future family.

The new microcontroller solutions are available now for sampling. Starter kits including an evaluation board, a free tool chain, comprehensive documentation including code examples and DAvE support can be ordered at Infineon or via the web shop of hitex.. In addition USB application kits are available for the XC800 family called USCALE and for the XE166 family called UCONNECT.

The XC864 is packaged in a TSSOP-20 and the XC886 HOT in a TQFP-48. The XE162M comes in a LQFP-64 package, the XE164M in a 100-pin LQFP package and the XE167M in a 144-pin LQFP package. The TC1167 is packaged in a LQFP-176 whereas the TC1197 is packaged in a BGA-416.

In quantities of 20,000 units, the 8bit XC864 is priced at about $1.05 per unit and the XC886 HOT at $3.08. The price of the 16bit XE166M series starts with the XE162M at about $7 each. The unit price of the 32bit TC1167 is about $20.16 and the TC1197 at $26.46.
