5 / 104 page MB90520B Series DS07-13707-5E 5 (Continued) *1 : As for the necessity of a DIP switch setting (S2) when using the emulation pod (MB2145-507) . Refer to the hardware manual for the emulation pod (MB2145-507) fomr details. *2 : Take note of the maximum operating frequency and A/D converter precision restrictions when operating at 3.0 V to 3.6 V. See the “Electrical Characteristics” section for details. Part Number Parameter MB90522B MB90523B MB90F523B MB90V520A Clock timer 15-bit timer Interrupt interval : 0.438, 0.5, or 2.0 µs for sub-clock frequency = 32.768 kHz 8/16-bit PPG timer Number of channels : 1 (Can be used in 2 × 8-bit channel mode) Can generate a pulse waveform output with specified period and 0 to 100 % duty ratio. 8/16 -bit up/down counter/timers Number of channels : 1 (Can be used in 2 × 8-bit channel mode) External event inputs : 6 channels Reload/compare function : 8-bit × 2 channels Clock monitor Clock output frequency : Machine clock/21 to machine clock/28 Delayed interrupt generation module Interrupt generation module for task switching. (Used by REALOS.) DTP/External interrupts Input channels : 8 Generates interrupts to the CPU on rising edges, falling edges with input “H” level, or “L” level. Can be used for external event interrupts and to activate EI2OS. Wakeup interrupts Input channels : 8 Triggered by “L” level. 8/10-bit A/D converter (successive approximation type) Number of channels : 8 Resolution : 8-bit or 10-bit selectable Conversion can be performed sequentially for multiple consecutive channels. • Single-shot conversion mode : Converts specified channel once only. • Continuous conversion mode : Repeatedly converts specified channel. • Intermittent conversion mode : Converts specified channel then halts temporarily. 8-bit D/A converter (R-2R type) Number of channels : 2 Resolution : 8-bit UART (SCI) Number of channels : 1 Clock synchronous transfer : 62.5 Kbps to 1 Mbps Clock asynchronous transfer : 1202 bps to 31250 bps Supports bi-directional and master-slave communications. Extended I/O serial interface Number of channels : 2 Clock synchronous transfer : 31.25 Kbps to 1 Mbps (Using internal shift clock) Transmission format : Selectable LSB-first or MSB-first LCD controller/driver Number of common outputs : 4 Number of segment outputs : 32 Number of power supply pins for LCD ttdrive : 4 LCD display memory : 16 bytes Divider resistor for LCD drive : Internal |
