MB9B360L Series

Clock and Reset

[Clocks]

Five clock sources (2 external oscillators, 2 internal CR

oscillator, and Main PLL) that are dynamically selectable.

Main clock:

4 MHz to 48 MHz

Sub Clock:

32.768 kHz

High-speed internal CR Clock: 4 MHz

Low-speed internal CR Clock: 100 kHz

Main PLL Clock

[Resets]

Reset requests from INITX pin

Power on reset

Software reset

Watchdog timers reset

Low voltage detector reset

Clock supervisor reset

Clock Super Visor (CSV)

Clocks generated by internal CR oscillators are used to

supervise abnormality of the external clocks.

External OSC clock failure (clock stop) is detected, reset is

asserted.

External OSC frequency anomaly is detected, interrupt or

reset is asserted.

Low-Voltage Detector (LVD)

This Series include 2-stage monitoring of voltage on the VCC

pins. When the voltage falls below the voltage has been set,

Low-Voltage Detector generates an interrupt or reset.

LVD1: error reporting via interrupt

LVD2: auto-reset operation

Low-Power Consumption Mode

Six low-power consumption modes are supported.

SLEEP

TIMER

RTC

STOP

Deep standby RTC (selectable from with/without RAM

retention)

Deep standby stop (selectable from with/without RAM

retention)

VBAT

The consumption power during the RTC operation can be

reduced by supplying the power supply independent from the

RTC (calendar circuit)/32 kHz oscillation circuit. The following

circuits can also be used.

RTC

32 kHz oscillation circuit

Power-on circuit

Back up register: 32 bytes

Port circuit

Debug

Serial Wire JTAG Debug Port (SWJ-DP)

Unique ID

Unique value of the device (41-bit) is set.

Power Supply

Three Power Supplies (when 64 pin Package)

Two Power Supplies (when 48 pin Package)

Wide range voltage:

VCC

= 2.7 V to 5.5 V

Power supply for USB I/O:

USBVCC = 3.0 V to 3.6 V (when USB is used)

= 2.7 V to 5.5 V (when GPIO is used)

Power supply for VBAT (only 64 pin Package):

VBAT

= 2.7 V to 5.5 V
