Features Flash ROM • Capable of on-board-programming with wide range, 3.0 to 5.5V, of voltage source. • Block-erasable in 128 byte units • 32768 × 8 bits RAM 2048 × 9 bits Minimum Bus Cycle • 250ns (4MHz) VDD=2.4V to 3.6V Note: The bus cycle time here refers to the ROM read speed. Minimum instruction cycle time • 750ns (4MHz) VDD=2.4 to 3.6V * This product is licensed from Silicon Storage Technology, Inc. (USA), and manufactured and sold by SANYO Semiconductor Co., Ltd.

During the HALT mode, program execution is stopped but peripheral circuits keep operating (Some parts of serial transfer operation stop.) (1) Oscillation circuits are not stopped automatically. (2) Released by the system reset or interrupts. • HOLD mode HOLD mode is used to reduce power consumption. Program execution and peripheral circuits are stopped. (1) CF, RC and crystal oscillation circuits stop automatically. (2) Released by any of the following conditions. 1) Low level input to the reset pin 2) Watchdog timer interrupt 3) Specified level input to one of INT0, INT1, INT2 4) Port 0 interrupt 5) SPI interrupt by receiving 1-byte (8-bit clock) • X’tal HOLD mode X’tal HOLD mode is used to reduce power consumption. Program execution is stopped. All peripheral circuits except the base timer are stopped. (1) CF and RC oscillation circuits stop automatically. (2) Crystal oscillator operation is kept in its state at HOLD mode inception. (3) Released by any of the following conditions. 1) Low level input to the reset pin 2) Watchdog timer interrupt 3) Specified level input to one of INT0, INT1, INT2 4) Port 0 interrupt 5) Base-timer interrupt 6) RTC interrupt 7) SPI interrupt by receiving 1-byte (8-bit clock) Onchip debugger • Supports software debugging with the IC mounted on the target board.
