MCUs have a huge 32Kbyte of RAM on-chip
Hitachi Europe has announced the immediate availability of a new series of 16bit microcontrollers featuring 32Kbyte on-chip RAM - the first in the industry to do so.
Most integrated GSM RF transceiver so far
Hitachi has launched its most integrated GSM RF transceiver solution to date.
The device offers 16bit performance and a range of peripherals more powerful than those on a typical low-end 8bit device, for a similar price.
This combination makes it ideal for a variety of applications, in particular those that currently use an 8bit microcontroller and require greater CPU performance.
The addition of on-chip EEPROM makes the H8/3664N suitable for applications that require nonvolatile storage of initialisation or calibration information, such as meters or motion control systems, security systems and communication systems where passwords or other addressing information must be stored.

Circular beam is a bonus for red laser diodes
Hitachi has announced the MARU Beam Series of red laser diodes which offers the world's first circular beam with a 1.2 (typical) aspect ratio in the 635nm wavelength band.
It also targets the H8/3664N at applications that already use the H8/3664F with an external EEPROM, as the devices are pin, function and software compatible.
In addition to the embedded EEPROM, the H8/3664N also has 32kbytes of on-chip single supply Flash memory.
This allows easy reprogramming of the memory without any additional circuitry and provides for easy end of line production programming, reducing customer inventory and software updates or bug fixes in the field.
The on-chip I2C interface enables communication with a wide range of peripherals and makes the device appropriate for many consumer applications, such as radios and stereos, where I2C is the de facto communications standard, and set top boxes, where it can be used as a low cost systems controller for handling housekeeping and I/O functions.
It also makes it suitable for Internet enabled products and industrial applications, such as intelligent sensors.
The H8/3664N is also suitable for many timer intensive applications as its powerful integrated 16bit timer module is capable of operating in a number of modes.
These applications include low-end motor control, for example in white goods.
The on-chip watchdog timer incorporates a built-in oscillator that simplifies the design of safety critical systems and provides an independent, resilient clock source.
The H8/3664N has a low operating voltage of just 3.0 to 5.5V and excellent EMC performance.
The device is a member of the H8/3664 series of microcontrollers which also includes a variety of mask ROM versions, with ROM sizes from 8 to 32Kbyte, and RAM sizes from 512byte to 2Kbyte.
Other peripherals include two 8bit timers, a high-speed USART, eight channels of 10bit A/D convertor and 37 I/O pins.
The device is shipped in a 64-pin QFP.
