8bit MCUs highlight dual-operation flash memory

Tuesday, April 21st, 2009

Fujitsu Microelectronics Europe has expanded its portfolio of low pin count microcontrollers with three new series in its F2MC-8FX family of high-performance 8bit MCUs featuring 8, 16, and 20 pins. The MB95260H, MB95270H and MB95280H series contain embedded dual-operation flash memory and support E2PROM emulation, which allows a reduction in system cost, as E2PROM does not need to be connected to the microcontroller.

In recent years, there has been rapidly growing demand for low pin count 8bit MCUs for use in home appliances such as white goods, water heaters, electric pots, de-humidifiers and hair dryers. In response to these needs, Fujitsu has been providing a line-up of 8-pin, 16-pin, and 20-pin low pin count 8bit flash MCUs in its F2MC-8FX family. The new MB95260H, MB95270H and MB95280H series are pin-compatible with previous MB95200 series products, with the addition of embedded dual-operation flash memory. This dual-operation flash provides memory for program data, as well as a memory area for data storage that eliminates the need for external E2PROM, and thus reduces total system cost.

In addition to their use as main MCUs, the three new series can be used as sub-microcontrollers. The new series also employ a single-line on-chip debug that uses only one pin on the microcontroller.

Key benefits
The new series include Fujitsu’s proprietary embedded dual-operation flash memory, which emulates E2PROM. The memory contains two regions, one for program storage, and another that can be used for data storage and acts as a substitute for E2PROM.

The microcontrollers also incorporate Fujitsu’s high reliability, high-performance embedded flash memory that can be re-written 100,000 times and guaranteed to hold data for 20 years. A flash security function protects customers’ software from being read by unauthorized external programs.

In addition, since the internal CR oscillating circuit and the low-voltage detection circuit are built into the microcontrollers, the need for an external oscillator and reset IC is eliminated, thus contributing to a reduction in overall system costs.

As for the timer function in the embedded ‘composite timer’, depending on the program, a channel can be selected from any one of the following: pulse width modulation, pulse width counter, interval timer or input capture which measures interval times. This provides the flexibility to handle customers’ varying system requirements.

Samples of the new series are already shipping. A starter kit, MB2146-420A-01-E, which includes the product development environment Softune Workbench, is also available.

Nuove serie di microcontroller a 8 bit

Friday, April 17th, 2009

Fujitsu Microelectronics Europe ha ampliato la sua linea di microcontroller “low pin-count” (LPC) con tre nuove serie di microcontroller a 8 bit ad alte prestazioni della famiglia F2MC-8FX, con 8, 16 e 20 pin. Le serie MB95260H, MB95270H e MB95280H contengono una memoria flash dual-operation e supportano l’emulazione E2PROM che consente di ridurre i costi di sistema in quanto l’E2PROM non richiede una connessione con il microcontroller.

La domanda di microcontroller a 8 bit a basso numero di pin per elettrodomestici, scaldabagni, bollitori, deumidificatori e asciugacapelli è cresciuta rapidamente negli ultimi anni. Per poter soddisfare queste esigenze, Fujitsu Microelectronics ha creato una linea di microcontroller flash a 8 bit con 8, 16 e 20 pin da inserire nella famiglia F2MC-8FX.

Le nuove serie MB95260H, MB95270H e MB95280H sono pin compatibili con la serie MB95200 e in più sono dotate di una memoria flash dual-operation embedded che fornisce un’area per i dati di programma e un’area per il salvataggio dei dati, eliminando la necessità di una E2PROM esterna e riducendo così i costi di sistema complessivi.

Oltre a essere usati come microcontroller principali, i prodotti delle tre nuove serie possono fungere anche da microcontroller secondari. La nuova serie è inoltre dotata di uno strumento di debug on-chip single-line che usa un solo pin sul microcontroller.

Fujitsu adds microcontrollers to F2MC-8FX family

In recent years, there has been rapidly growing demand for LPC 8-bit microcontrollers for use in home appliances such as white goods, water heaters, electric pots, dehumidifiers and hair dryers, according to the company.

In response to these needs, Fujitsu has been providing a line-up of eight-, 16- and 20-pin LPC 8-bit flash microcontrollers in its F2MC-8FX family.

This provides the flexibility to handle customers’ varying system requirements.
