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 new microcontrollers are also available in Flexible Zero Turn-Around Time (F-ZTAT) versions with on-chip Flash memory.
The H8/3694 devices are based on Hitachi's H8/300H CPU core and with a 5V power supply boast a maximum operating frequency of 20MHz - 4MHz higher than current models.
This provides increased processing power for the development of high-performance end products.

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 new microcontrollers also offer a low pin-count up to a maximum of 64 and 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.
The devices can be used for a wide range of functions, including main controller in small products to subcontroller in larger products.
The new devices are ideal for systems that require low noise levels as their internal power supply wiring has been optimised to minimise electromagnetic interference.
They also feature power-on reset and low-voltage detection functions which can be useful when designing products that are subject to battery power supply voltage fluctuations or require system protection.
The H8/3694F F-ZTAT version of the series incorporates Flash memory that can be programmed and erased with a single power supply.
This enables on-chip 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 H8/3694 series is available in a 64-pin LQFP (10 x 10mm) and a QFP (14 x 14mm), offering pin compatibility with Hitachi's H8/3664 series.
The new series will also be available in two 48-pin LQFPs (10 x 10 and 7 x 7mm), allowing significantly smaller systems to be designed.
