Microcontroller Roundup

Our roundup of microcontroller technologies covered in recent issues of Arrow Innovation looks at three devices: Infineon’s 32-bit TC116x chip aimed at real-time and motor control; the TMP86FH92, an advanced 8-bit device from Toshiba optimised for industrial and automotive use; and the SH7203, a single-chip industrial PC from Renesas Technology.

The TC116x series 32-bit Flash microcontrollers from Infineon are designed for demanding real-time control applications. The devices can replace conventional solutions which require a separate microcontroller, DSP and PWM ASIC, boosting power efficiency, reducing system costs by up to 40%, and cutting board space, system size and complexity.



Features

• 32-bit Flash microcontroller delivering 80MIPS to 100MIPS
• TriCore™ architecture combining RISC, CISC and DSP-type functions
• Single software environment
• 1Mbit to 1.5Mbit Flash memory
• 16Kbit or 32Kbit EEPROM
• 40Kbit to 72Kbit RAM
• Very fast real-time operation and interrupt system
• Powerful and flexible peripheral set
• GPTA® for PWM generation
• Optional MultiCAN™
• Fast multi-channel ADCs
• Asynchronous and Synchronous Serial Interfaces (ASC/SSC)
• Micro Link Interface (MLI) for connection with a second controller

Toshiba's compact TMP86FH92 8-bit CMOS microcontroller combines 16KByte of SuperFlash memory with a large number of serial interfaces and new analogue IP blocks for LVD (Low Voltage Detector) and POR (Power On Reset) functions. The device is based on Toshiba's low-power, high-performance TLCS870/C core and is suited to automotive and industrial applications including actuator control, sensor interfacing and power supervision. A fully automotive-qualified version of the device is available.



Features

• Compact 30-pin SSOP package
• 16KByte Flash
• Many serial interfaces: two UARTs, SPI, I²C
• New analogue IPs for LVD and POR
• Fully automotive-qualified version available

The SH7203 from Renesas Technology includes all of the features needed to implement a single-chip industrial PC, requiring only the addition of external memory. Incorporating a high-performance floating-point core, USB v2.0 interface, display controller and CAN controllers, the device delivers performance of 480MIPS (Dhrystone).

The CPU architecture is optimised to execute code written in C and C++. Most instructions are 16 bits in length, allowing two instructions to be fetched in each 32-bit memory access. This, combined with the device’s 16Kbyte on-chip memory, ensures fast program execution.



Features

• 200MHz SH-2A superscalar RISC microcontroller operating at 480DMIPS
• IEEE754-compliant FPU with single- and double-precision operations
• 15 register banks for fast interrupt handling
• 16Kbyte cache memory
• Two-channel CAN controller supporting CAN specification 2.0B
• USB v2.0 compliant high-speed (480Mbit/s) interface with Host or Function support
• LCD controller drives STN, dual-STN and TFT display panels up to 800 x 480 pixels
• On-chip MTU2 block provides six 16-bit timer channels, CAPCOM, PWM generation
• Powerful three-phase complementary PWM mode with automatic deadtime insertion
• Eight-channel 10-bit ADC with 3.9µs conversion time
• Four serial communication interfaces; four I²C bus interfaces
• 240-pin QFP
