78K0 CPU core
　　I/O ports, ROM and RAM capacities
　　Low power consumption (VDD = 3.0 V)
　　* Internal high-speed oscillation mode:   220
　　* STOP mode:    0.65
　　Clock
　　* High-speed system clock … Selected from the following three sources
　　- Ceramic/crystal oscillator:    1 to 10 MHz
　　- External clock:    1 to 10 MHz
　　- Internal high-speed oscillator:   4 MHz ± 2 % (-20 to +70°C), or 8 MHz ± 3 %(-40 to +85°C)
　　* Low-speed system oscillator    30 kHz ± 10 % … Watchdog timer, timer clock in intermittent operation
　　* Subsystem clock:    Clock to operate the real-time counter mainly
　　Timer
　　* 16-bit timer/event counter …  PPG output, capture input, external event counter input
　　* 8-bit timer H …   PWM output
　　* 8-bit timer/event counter 5 … PWM output, external event counter input
　　* Watchdog timer …  Operable with low-speed internal oscillation clock
　　* Real-time counter …  Available to count up in year, month, week, day, hour, minute, and second units
　　Serial interface
　　* UART …  Asynchronous 2-wire serial interface
　　* IICA …  Clock synchronous 2-wire serial interface, multimaster supported, standby can be released upon address match in slave mode
　　* CSI …  Clock synchronous 3-wire serial interface
　　10-bit resolution A/D conversion
　　* 78K0/KY2-L:  4 ch
　　* 78K0/KY2-L, 78K0/KA2-L:  1 ch
　　Power-on-clear (POC) circuit
　　Low-voltage detector (LVI) (An interrupt/reset (selectable) is generated when the detection voltage is reached))
　　* Detection voltage: Selectable from sixteen levels between 1.91 and 4.22 V
　　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
　　Development tools
　　* Support for full-function emulator (IECUBE), and simplified emulator (MINICUBE2)
　　Power supply voltage: VDD = 1.8 to 5.5 V
　　Operating ambient temperature: TA = -40 to +85°C
