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 is also suitable for ISDN equipment and industrial applications such as gas-water-electricity metering, sensors, or portable medical applications such as blood pressure and blood sugar meters.
Multichip systems require much more board space and usually consume considerably more power than comparable single-chip systems.
Integrating large memories on-chip helps reduce both space and power consumption.
Therefore, as many low power applications also have tough space constraints, the H8S/2239F is ideal for ultra-compact, low-power, quick-to-assemble and highly reliable systems.
The microcontroller typically uses 30mA at its full clock speed of 20MHz and at 3V but it has a specified minimum clock of 2MHz where it consumes only 4mA.
This can be further improved by turning off unused modules.
The microcontroller's efficient H8S CPU enables the chip's 20MHz clock to yield up to 16MIPS native peak performance or about 8MIPS Dhrystone.
Other low-power features include a 32kHz subclock and the low power modes associated with that.
The H8S/2239F is pin-compatible with all other derivatives in the H8S/223x series, including the popular H8S/2238RF, allowing easy migration upwards towards increased software functionality.
The device has a comprehensive peripheral set including 4 channel serial ports supporting async, sync, I2C and ISO7816-3, a four-channel DMA and Hitachi's popular versatile data transfer controller (DTC), a flexible DMA-like function.
It also features a six-channel 16bit timer unit with up to 16 input capture/output compare registers, an eight-channel 10bit ADC, a two-channel 8bit DAC, 72 IO lines and 10 input lines, some of which feature programmable pull-up, open drain and Schmitt trigger functionality.
The H8S/2239F is available in three different 100-pin package options, a low cost QFP and two TQFPs, one of which is a very compact 0.4mm pin pitch package that measures just 12 x 12mm.
The H8S/2239F is supported by the E6000 emulator and by Lauterbach's Trace32-Fire.
