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.
It features a popular mix of memory and peripherals, combined with low power consumption, high CPU performance, and near-pin-compatibility (one pin difference) with the H8S/2357F.
The device is general purpose, suitable for many application areas such as consumer, industrial, telecomms and automotive.
The H8S/2398F uses the same E6P2655 E6000 emulator for development as the older H8S/2357F, enabling customers to re-use their existing development suite.
The device offers 5V/20MHz operation, which is achieved by means of an on-chip voltage regulator that converts the external power supply to the requirements of the internal logic.
As with all H8S microcontrollers, the device features a high performance, single-cycle CPU, which yields 8MIPS Dhrystone at 20MHz.
It also has a low power consumption of just 70mA (typical at 20MHz) and includes several low power features to reduce this further.
The device features a powerful six-channel 16bit timer unit (TPU) with up to 16 input capture or output compare units.
It also features a direct memory access (DMA) and Hitachi's data transfer controller (DTC), a versatile pseudo-DMA with advanced features, such as the possibility to trigger more than one transfer by a single event.
It has three serial ports (USART), which support asynchronous and synchronous operation as well as a subset of ISO7816 (smart card mode).
The programmable pulse generator (PPG) allows the output of a stream of data patterns at up to 16 pins under timer control.
This avoids the jitter associated with interrupt driven CPU services.
The H8S/2398F also features an eight-channel 10bit ADC, a two-channel 8bit DAC, 87 IO pins and eight input-only lines, some of which have programmable pull-ups, Schmitt trigger characteristics and 10mA drive capability.
The new device is available now in a 128-pin QFP and will be followed by a 120-pin TQFP in Q2 2002.
