The SH7710 32bit RISC microprocessor features an IPsec accelerator for fast encryption and communication processing.
A 16bit timer module allows the automatic control of many types of motor such as two and three phase brushless and asynchronous motors.
This provides a cost-optimised solution where previously a DSP or higher-cost micro-controller would have had to be used.
Renesas' existing H8/36077LF offers 32 and 56Kbyte of on-chip single-supply Flash memory.
The new H8/36079LF offers 128Kbyte and the H8/36078 offers 96Kbyte.
The H8 on chip flash allows the easy reprogramming of the memory without any additional special circuitry.
This allows easy end of line programming, reducing customer inventory, software updates or bug fixes in the field.
Large on-chip SRAM makes the H8/36079LF ideal for applications that require a lot of data handling and calculation such as motor control applications.
The on-chip real-time clock means the device is able to keep time accurately using a standard 32kHz watch crystal, and can therefore provide a true single-chip motor control and user interface solution for many applications.
The on-chip I2C Interface allows the H8/36079LF to interface with a variety of peripherals such as serial EEPROMs and telecoms ICs, as well as other micro-controllers.
Two high-speed serial ports combined with up to 6Kbyte of SRAM also make the device ideal for applications where communications are required.
The addition of a watchdog timer with independent on-chip oscillator and power on reset, and low voltage detection circuits simplifies the design of safety critical systems.
The H8/36079LF also provides a solution for many applications that are becoming internet enabled, as it has both the CPU performance and the communication capabilities required for such applications.
Two high-speed serial ports combined with up to 6Kbyte of SRAM for buffering make the device ideal for communications gateways and protocol convertors.
The H8/36079LF also has a range of peripherals, with two high-speed USARTs along with a multi-master I2C channel, along with the eight channels of 10bit A/D.
The I2C makes the H8/36079LF interesting in many consumer applications, such as set top boxes where it can be used as a low-cost systems controller for handling the housekeeping and I/O functions.
It can also be used in other consumer products such as radios and stereos, where I2C is the de facto communications standard.
Development tools for use with the H8/36079LF are the E8 emulator and the MB3687 evaluation board.
