MB89595B

The MB89595B/BW series is a line of general-purpose, single-chip microcontrollers. The USB hub function, in particular, supports five ports (one of them is dedicated to an internal function) allowing them to interface with other USB devices. The microcontrollers also contain one USB function channel to support high speeds. In addition to a compact in-struction set, these microcontrollers contain a variety of peripheral functions, such as PLL clock control, timers, a serial interface, a PWM timer, the USB hub function, and the USB function.

The features of MB89595B can be summarized as (1)package type, 64-pin LQFP package (0.5 mm pitch); (2)high-speed operations at low voltage, minimum execution time : 0.33 ms (Automatically generates a 12 MHz main clock and a 48 MHz USB interface synchronization clock with an externally supplied 6 MHz clock and the internal PLL circuit.); (3)F2MC-8L CPU core; (4)various timers; (5)internal USB transceiver circuit (compatible with high and low speeds); (6)USB hub; (7)USB function; (8)UART/serial interface; (9)external interrupt; (10)low power consumption (standby mode supported); (11)a maximum of 45 general-purpose I/O ports; (12)power supply.

The absolute maximum ratings of MB89595B are (1)power supply voltage VCC: VSS - 0.3/VSS + 6.0 V; (2)input voltage VI: VSS - 0.3/VCC + 0.3 V; (3)output voltage VO: VSS - 0.3/VCC + 0.3 V; (4)"L" level average output current IOLAV: 4 mA; (5)"L" level total maximum output current IOL: 100 mA; (6)"L"level total average output current IOLAV: 40 mA; (7)"H"level maximum output current IOH: -15mA; (8)"H"level average output current IOHAV: -4 mA; (9)"H"level total maximum output current IOH: -50 mA; (10)"H"level total average output current IOHAV: -20 mA; (11)power consumption PD: 300 mW; (12)operating temperature TA: -40 +85°C; (13)storage temperature Tstg: -55 +150°C.
