LONDON – Fujitsu Semiconductor Europe has introduced a second generation 8-bit microcontroller featuring embedded FRAM (Ferroelectric Random Access Memory).
The MB95R203A includes 64-kbits (8-kbytes) of user-accessible FRAM, which can be partitioned as either ROM or RAM. The ability to change data and work memory space makes the device suitable for some applications and programming requirements.
The read/write endurance is specified as 1015 times, with data retention guaranteed for 10 years. The high speed non-volatile nature of FRAM offers the advantage that it writes so fast that the MCU does not need to wait for the write operation to complete. This high-speed write operation allows data to be written quickly even if power is lost suddenly.
It operates with power supplies ranging from 1.8 to 3.6V – 1.8V power supplies are typically used in home healthcare devices, such as blood pressure and glucose meters. It incorporates timers and communication functions, as well as high-precision A/D converters, UART, I2C, and 16 I/O ports. The controller employs one-line on-chip debug, which requires only a single MCU pin. An embedded oscillator circuit maximises the number of pins available for use in smart meters, consumer appliances, electric tools, and other product designs.
The MB95R203A is shipped in 20-pin SOP packages. Samples are available now and production quantities will be ready by the end of November 2010, the company said. No price was given for the part.
