2 / 104 page  MB90520B Series 2 DS07-13707-5E • Sub-clock (32.768 KHz) operation available Minimum instruction execution time : 62.5 ns (for oscillation = 4 MHz, PLL clock setting = ×4, VCC = 5.0 V) • 16MB CPU memory space Internal 24-bit addressing • Instruction set optimized for controller applications Rich data types (bit, byte, word, long-word) Extended addressing modes (23 types) Enhanced signed multiplication and division instructions and RETI instruction Enhanced calculation precision using a 32-bit accumulator • Instruction set designed for high-level language (C) and multi-tasking System stack pointer Enhanced pointer-indirect instructions and barrel shift instructions • Faster execution speed 4-byte instruction queue ROM mirror function (48 Kbytes of bank FF is mirrored in bank 00) • Program patch function : An address match detection function (2 × addresses) • Interrupt function 32 programmable interrupts with 8 levels • Automatic data transmission function independent of CPU operation Extended intelligent I/O service function (EI2OS) : Up to 16 channels • Low-power consumption (stand-by) modes Sleep mode (CPU operating clock stops, peripherals continue to operate.) Pseudo-clock mode (Only oscillation clock and timebase timer continue to operate.) Clock mode (Main oscillation clock stops, sub-clock and clock timer continue to operate.) Stop mode (Main oscillation and sub-clock both stop.) CPU intermittent operation mode Hardware stand-by mode (Change to stop mpde by operating hardware stand-by pins.) • Process CMOS technology • I/O ports General-purpose I/O ports (CMOS input/output) : 53 ports General-purpose I/O ports (inputs with pull-up resistors) : 24 ports General-purpose I/O ports (N-ch open-drain outputs) : 8 ports • Timers Timebase timer, clock timer, watchdog timer : 1 channel each 8/16-bit PPG timers 0 and 1 : 8-bit × 2 channels or 16-bit × 1 channel 16-bit reload timers 0 and 1 : 2 channels 16-bit I/O timers : 16-bit free-run timers 0 and 1 : 2 channels 16-bit input capture 0 : 2 channels (2 channels per unit) 16-bit output compare 0 and 1 : 8 channels (4 channels per unit) 8/16-bit up/down counter/timers 0 and 1 : 8-bit × 2 channels or 16-bit × 1 channel Clock output function : 1 channel • Communications macro (communication interface) Extended I/O serial interfaces 0 and 1 : 2 channels UART (full-duplex, double-buffered, SCI : Can also be used for synchronous serial transfer) : 1 channel (Continued) |
