MB9B360R Series

CRC (Cyclic Redundancy Check) Accelerator

The CRC accelerator helps a verify data transmission or

storage integrity.

CCITT CRC16 and IEEE-802.3 CRC32 are supported.

CCITT CRC16 Generator Polynomial: 0x1021

IEEE-802.3 CRC32 Generator Polynomial: 0x04C11DB7

SD Card Interface

It is possible to use the SD card that conforms to the following

standards.

Part 1 Physical Layer Specification version 3.01

Part E1 SDIO Specification version 3.00

Part A2 SD Host Controller Standard Specification version

3.00

1-bit or 4-bit data bus

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)

Embedded Trace Macrocells (ETM) provide comprehensive

debug and trace facilities.

Unique ID

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

Power Supply

Three Power Supplies

Wide range voltage :

VCC

= 2.7V to 5.5V

Power supply for USB I/O :

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

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

Power supply for VBAT :

VBAT

= 2.7V to 5.5V
