Sunnyvale, Calif. - Fujitsu Microelectronics says its latest 16- and 32-bit microcontrollers deliver excellent performance for digital consumer products with power requirements as low as 1 milliamp per megahertz.
The 32-bit MB91F233 and MB9-1232L devices, part of the FR60Lite series, incorporate embedded LCD controllers and are designed for use in mobile products and digital consumer electronics. Two other members, designated the MB91263 and MB91F264, are designed for consumer appliances that require motor control or inverter control.
The MB91F233 is specified for a maximum supply current of 80 mA and has 256 kbytes of flash ROM and 16 kbytes of RAM. The MB91232L, which has a maximum current of 50 mA, has 192 kbytes of ROM along with 16 kbytes of RAM. Both operate on voltages ranging from 2.4 to 3.6 V, with a maximum frequency of 33 MHz.
Prices for the MB91F233, which is packaged in a 120-pin low-profile quad flat pack, start at $10.72 each in 10,000-piece quantities. The MB91232L sells for $7.23 each in 50,000-piece quantities. Packaged in a 100-pin QFP, the MB91F264 starts at $8.42 each in lots of 10,000 and the MB91263 at $4.25 each in 50,000-piece quantities.
Meanwhile, four new members of Fujitsu's MB90800 series have been developed specifically for LCD panels that must display large segment counts.
The MB90F804-101 and MB90F804-201 incorporate 16 kbytes of RAM and 256 kbytes of flash; and the MB90803 and MB90803S provide 4 kbytes of RAM and 128 kbytes of ROM. Each operates at 25 MHz, requires a power supply of 3 to 3.6 V and delivers a minimum instruction execution time of 40 nanoseconds at frequencies of 6.25 MHz external or 25 MHz internal.
The LCD controllers also include a two-channel UART, two-channel serial I/O interface and single-channel I2C bus interface. A 12-channel A/D converter is on board all four versions, along with a complete set of timers and standby modes for maximum power conservation.
Prices for the MB90F804-101 and MB90F804-201 in 100-pin QFPs start at $12.31 each in 10,000-unit quantities; the MB90803 and MB90803S start at $5.76 each in 50,000 units.
