5 / 18 page MB9B100 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 Clock and Reset [Clocks] Five clock sources (2 ext. osc, 2 CR osc, and PLL) that are dynamically selectable. ・ Main Clock : 4 to 48MHz ・ Sub Clock : 32.768kHz ・ High-speed CR Clock : 4MHz ・ Low-speed CR Clock : 100kHz ・ PLL Clock [Resets] Reset requests from INITX pins, Power on reset, Software reset, watchdog timers reset, low voltage detector reset and clock supervisor reset. Clock Super Visor (CSV) Clocks generated by 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) MB9B100 Series include 2-stage monitoring of voltage on the VCC. 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 Mode Three power saving modes supported. ・ SLEEP ・ TIMER ・ STOP Debug ・ Serial Wire JTAG Debug Port (SWJ-DP) ・ Embedded Trace Macrocells (ETM) provide comprehensive debug and trace facilities. ・ Trace Port Interface Unit (TPIU) for bridging to a Trace Port Analyzer. Power Supply Two Power Supplies ・ VCC = 2.7V to 5.5V: Correspond to the wide range voltage. 5 FUJITSU SEMICONDUCTOR CONFIDENTIAL r2.1 DS706-00007-1v0-E |
