DESCRIPTION
The MB89590B/BW series is a line of general-purpose, single-chip microcontrollers. 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 USB hub function, in particular, sup-
ports 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.

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 : Internal system clock oscillated at 12 MHz)
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 high and low speeds)
USB hub
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 information is provided as ROM data for automatic responding by hardware (vendor
ID and product ID) .
* String data is not supported.
Allows switching between BUS power supply and own power supply modes.
Power supply to the USB down ports is controlled port by port.
USB function
Compliant to USB Protocol Revision 1.0
Support for full speed
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/serial interface
Built-in UART/SIO function (selectable by switching)
External interrupt
External interrupt (level detection
8 channels)
Eight inputs are independent of one another and can also be used for resetting from low-power consumption
mode (the L-level detection feature available) .
Low power consumption (standby mode supported)
Stop mode (There is almost no current consumption since oscillation stops.)
Sleep mode (This mode stops the running CPU.)
A maximum of 45 general-purpose I/O ports
General-purpose I/O ports (CMOS) : 34
General-purpose output ports (CMOS) : 8
General-purpose I/O ports (Nch open drain) : 3
Power supply
Supply voltage : 3.0 to 5.5 V

DIFFERENCES AMONG PRODUCTS
1.
Memory Size
Before evaluating using the OTP product, verify its differences from the product that will actually be used.
2.
Current Consumption
When operated at low speeds, a product mounted with either one-time PROM or EPROM consumes more
current than a product mounted with a mask ROM. However, in sleep/stop mode the current consumption is the
same.
For detailed information on each package, see "
s
PACKAGE DIMENSIONS."
3.
Differences Between the MB89590B series and the MB89590BW Series
MB89590B series :
Remains in high impedance state until USB connection takes place. Before the USB
connection, use one general-purpose port output to control pullup resistance connec-
tion of this port by software.
MB89590BW series : Outputs at low level until USB connection takes place.
