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.
All Tiny Series 16bit devices boast a low pin count and small package outlines.
The new microcontrollers are based on Hitachi's H8/300H CPU core and have a maximum of 64 pins.
Operating at a maximum frequency of 20MHz using a 5V power supply, compared to 16MHz for current models, the devices have increased processing performance enabling high-performance end products to be created.

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.
The H8/3687 series boasts enhanced timer and communication functions ideal for home appliance and industrial applications.
All new H8/3687 devices feature a comprehensive range of on-chip peripheral functions, including a subclock, sophisticated timers, 10bit analogue/digital convertor, asynchronous/synchronous serial interfaces, I2C bus interface, and large-current pins.
This permits the use of the microcontrollers in a wide range of roles, from main controller in small products to subcontroller in larger products.
Other peripherals include two 16bit time channels and two serial communication interface channels.
The internal power supply wiring of these new devices has been optimised to minimise electro-magnetic interference, making these models ideal for systems requiring low noise levels.
Power-on reset and low-voltage detection functions are available on all of the new microcontrollers and can be useful when designing products which are subject to battery power supply voltage fluctuations or require system protection.
The H8/3687F F-ZTAT version of the microcontroller incorporates flash memory that can be programmed and erased with a single power supply.
This enables onboard modification of control programs and system adjustment data for shorter system development times.
The new series is supported by the E6000 real-time, in-circuit emulator and the E10T, a low cost in-circuit debugging system.
The E6000 has 4Mbyte of emulation RAM, 256 PC break points and 12 cascadable and complex hardware break points (events).
It also includes a 32Kcycle and 80bit-wide trace buffer with acquisition and display filtering, execution time measurement and four user logic probes, which can also be used to trigger hardware events.
The E10T uses the on-chip debug facility of the microcontroller to provide the user with the ability to fully debug their application in the target system.
The H8/3687 microcontrollers are available in a 64-pin LQFP (10 x 10mm) and a 64-pin QFP (14 x 14mm).
