Flash micro enables single-chip control of two motors
19 June 2002, DSP, Micros & Memory

Hitachi's 32 bit single-chip RISC microcontroller, the SH7047F, features 256 KB of on-chip single-power-supply flash memory and two motor control timers.

This enables single-chip control of two motors that previously required two microcontrollers. This function, together with a 65 MIPS processing performance at 50 MHz operating frequency, enables high-precision motor control and efficient system control to be achieved with a single chip. Smaller, lower-priced systems for white-goods, industrial, and automotive applications are now possible claims the manufacturer.

Based on the SuperH SH-2 CPU core, the device is the successor to Hitachi's SH7040 series and comprises the first phase of its new 0,35 µm products. The finer process provides faster CPU and peripheral module operation in a more compact form. In addition to the flash SH7047F, the SH7049 ROM version is available, offering 128 KB of on-chip mask ROM.

Both devices offer a single 5 V power supply in place of the two power supply systems of previous products (5 V for the I/O ports and 3 V for the internal logic circuitry). This is achieved through the use of an on-chip step-down circuit and simplifies system construction. Both power consumption and noise have also been reduced as the internal logic circuits operate on a low stepped-down voltage.

In addition to an on-chip multifunction timer pulse unit (MTU) and a motor management timer (MMT), the SH7047F and SH7049 are equipped with a comprehensive selection of peripheral functions for application areas that need high-precision control and integrated processing of various kinds of control. For example, both devices offer two A/D converter units, each with eight channels, and both units are capable of operating simultaneously. Feedback control can thus be sped up - essential to high-precision motor control.

For communications, the SH7047F and SH7049 also incorporate HCAN2 (Hitachi controller area network), compatible with CAN (Version 2.0B), used in in-vehicle LANs and device networks. For a development environment, the SH7047F incorporates H-UDI and AUD on-chip debug functions. This enables simple emulation by using third party on-chip debug development tools. The SH7047F and SH7049 are available in a 100-pin QFP.
