Serial interface
UART6 … Asynchronous 2-wire serial interface
DALI … 2-wire serial interface for lighting control (slave)
IICA … Clock synchronous 2-wire serial interface, multimaster supported
standby can be released upon address match in slave mode
CSI11 … Clock synchronous 3-wire serial interface, operable as SPI in slave mode

10-bit resolution A/D conversion
78K0/IY2: 5 ch
78K0/IA2: 6 ch
78K0/IB2: 9 ch
Operational amplifier (Products with operational amplifier only): 1 ch
Comparator: 3 ch
Power-on-clear (POC) circuit
Low-voltage detector (LVI) circuit (An interrupt/reset (selectable) is generated when the detection voltage is
reached))
Detection voltage: Selectable from ten levels between 2.84 and 4.22 V
*1.91 V is used only when the power is turned on when the LVI default start is set.
Single-power-supply flash memory
Flash self programming enabled
Software protection function: Protected from outside party copying (no flash reading command)
Safety function
Watchdog timer operated by clock independent from CPU
… A hang-up can be detected even if the system clock stops
Supply voltage drop detectable by LVI
… Appropriate processing can be executed before the supply voltage drops below the operation voltage
Equipped with option byte function
… Important system operation settings set in hardware
On-chip debug function …Available to control for the target device, and to reference memory
Assembler and C language supported
Enhanced development environment
Support for full-function emulator (IECUBE), and simplified emulator (QB-MINI2)
Power supply voltage: V
DD = 2.7 to 5.5 V
Operating ambient temperature: TA = –40 to +105C
