DESCRIPTION
The MB89051 series is a general-purpose, single-chip microcontroller that features a compact instruction set and
contains a range of peripheral function set and timers, serial interface, a PWM timer, the USB hub function and
the USB function. The USB hub function, in particular, supports five down 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 full speed.

MC-8L CPU core
Instruction set that is optimum to the controllers
-Multiplication and division instructions
-16-bit arithmetic operations
-branch instructions by bit testing
-bit manipulation instructions, etc.
• PLL clock control
The internal PLL clock circuit allows the use of low-speed clocks which are advantageous to noise character-
istics.
(6 MHz externally-supplied clock→12 MHz internal system clock)
• Various timers
8-bit PWM timer (can be used as either 8-bit PWM timer 2 channels or PPG timer 1 channel)
Internal 21-bit timebase timer
• Internal USB transceiver circuit (Compatible with full and low speeds)
• USB hub
USB function Compliant to USB Protocol Revision 1.0
Five downstream port channels (One of these channels is dedicated to a function.)
Automatically responds to all USB protocols by hardware.
Descriptor configuration is provided as ROM data for automatic responding by hardware (Vender ID and product
ID) .
String data is not supported.
Allows switching between BUS power supply and own power supply mode.
Power supply to the USB down port is controlled port by port.
• USB function
USB function Compliant to USB Protocol Revision 1.0
Support for full speed when using hub
Support for both low and full speeds when using function
Allows four endpoints to be specified at maximum.
Types of transfer supported: control/interrupt/bulk/isochronous
Built-in DMAC (Maps the buffer for each endpoint on to the internal RAM to directly access the memory for
function’s send and receive data.)
• UART/SIO, SIO Serial Interface

DIFFERENCES AMONG PRODUCTS
1. Memory Size
• Before evaluating using the FLASH product, it is necessary to confirm its differences from the product that will
actually be used.
2. Current Consumption
• When operating at low speed, FLASH products will consume more current than mask ROM products. However,
in sleep/stop mode the current consumption is the same.
• For detailed information on each package, see “sPACKAGE DIMENSIONS”
3. USB Pull-up Resistor control
• Remains in high impedance state until USB connection take place. Before the USB connection, use USBP
pin output to control pull-up resistance by software.
