Renesas SH7286 has memory for motor contol
The SuperH SH7286 offers up to 1Mbyte of fast MONOS embedded flash memory that has been designed specifically for the high-end drives, AC servos and general-purpose inverter markets.
Dual-core processor powers up to 1920MIPS
The new SH7786 incorporates dual SH-4A high-performance 32bit RISC CPU cores, each with a processing performance of 960MIPS at 533MHz.
The device's on-chip real time clock provides an ideal solution for many time keeping applications, and the on-chip high-resolution 10bit A/D convertor with its wide sampling range makes the 38099F ideal for a variety of metering applications.
The on-chip watchdog timer with built in oscillator along with power on reset and the on-chip oscillator makes the H/38099F easy to design into systems where reliability is an issue.
The special design of USART with built in IrDA interface is designed to operate in a variety of low power modes, and can be driven at up to 1200baud from the 32kHz oscillator.
The device's powerful 16bit timer module can be used for a variety of purposes, including driving a variety of motors, and is capable of generating up to four channels of PWM output.
The H8/38099F has an on-chip LCD controller with its own voltage booster and constant voltage generator.
This can be programmed by the user to generate a constant voltage for the LCD, no matter what the input voltage to the microcontroller.
The device also supports digital contrast control.
The H8/38099F supports low power operation as follows, 1.1mA at 2MHz in active mode, 9A in subactive mode, 0.5A in watch mode with RTC operating, and 0.1A in standby mode.
The H8/38099RF has 128Kbyte of on-chip Flash and 4Kbyte of SRAM, and there are also 128 and 96byte mask-ROM versions for cost-sensitive applications.
The H8/38099RF features a 10MHz H8/300H CPU core, interfaces for SCI (three), clock sync and I2C, a 16bit timer, TPU (2 x 16bit), two 8bit timers, an asynchronous timer, watchdog timer with on-chip RC, four 14bit PWM, and an eight-channel 10bit A/D convertor.
Other features include a 40 x 4 LCD controller/driver, tuneable booster for LCD, 83 I/O pins, on-chip POR and an on-chip debug interface.
Applications for the H8/38099F are many and varied.
The device provides an ideal solution for metering applications, such as water and gas meters, as well as heat meters and heat allocators as a result of the combination of very low cost and low power consumption along with the advanced feature set.
The low cost of the H8/38099F also makes it ideal for many types of electricity meter.
The fast oscillator start up feature of the H8/38099F makes it ideal for applications that spends most of their time dormant in an extremely low power state, and then waken to take readings or to communicate.
Applications such as water meters, and gas meters are prime examples, along with many automated meter reading solutions (AMR) using low power RF or powerline.
The asynchronous timer on the H8/38099RF also makes the device ideal for battery powered applications that count pulses, as it is able to count external pulses and keep a real time clock function with an average power consumption of around 0.5uA.
Apart from metering, any other application where the system is required to be battery powered, take some reading or measurement and communicate, and normally with a user interface, are ideal applications for the 38099F.
Such applications include flow meters, security sensors, access control panels, various types of user interface, data loggers etc.
Development tools available for the device are the E8a emulator and the RSK38099 starter kit.
The Renesas H8/38099F series MCU is available now.
