Microcontroller boosts serial
communications
The H8/36014F MCU combines the high-performance 16bit H8/300H Tiny CPU core with two USARTs, capable of operating at up to 625kbaud in asynchronous mode and up to 4Mbit/s in synchronous mode.
The H8/36014F microcontroller combines Hitachi's high-performance 16bit H8/300H Tiny CPU core with two USARTs, capable of operating at up to 625kbaud in asynchronous (UART) mode, and up to 4Mbit/s in synchronous mode The new device is ideal for applications where two high performance serial channels are required, such as serial buffers, gateways and protocol converters

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 H8/36014F operates at a maximum frequency of 20MHz using a 3 to 5.5V power supply.
In addition to the two on-chip USARTs, it offers a wide variety of on-chip peripherals, including sophisticated 16bit timers as well as an 8bit timer, a 10bit analogue/digital convertor, and a number of high-current I/O pins.
The device is also designed for applications where reliability is key, as it features a watchdog timer with its own on-chip oscillator, optional power-on-reset and low voltage detection systems.
The new microcontroller is available in two Flash versions, the H8/36014F with 32Kbyte of single supply on-chip Flash, and the H8/36012F with 16Kbyte of on-chip Flash.
The Flash memory on both devices 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 H8/36014F 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 H8/36014F to provide the user with the ability to fully debug their application in the target system.
The new device is available in a variety of quad flat pack (QFP) packages: the 64-pin, 10 x 10mm QFP-64E; the 48-pin, 10 x 10mm QFP-48F; and the 80-pin, 7 x 7mm QFP-48B.
