78K0S/KY1+ Microcontrollers

Features

  • Supply voltage: VDD = 2.0 to 5.5 V
    * Use these products in the following voltage range because the detection voltage (VPOC) of the POC circuit is the supply voltage range.
    Standard product, (A) grade product: 2.2 to 5.5 V, (A2) grade product: 2.26 to 5.5 V
  • Max. Frequency 10 MHz
  • ROM capacities: 1 KB to 4 KB flash memory
  • RAM capacities: 128 bytes
  • 16-pin Plastic SSOP, SDIP and WLBGA package
  • 78K0S CPU core
  • Minimum instruction execution time: 0.2 µs (with 10 MHz @4.0 to 5.5 V operation)
  • Clock
    High-speed system clock ... Selected from the following three sources
    - Ceramic/crystal resonator: 2 to 10 MHz (Standard product, (A) grade product) / 2 to 8 MHz ((A2) grade product)
    - External clock: 2 to 10 MHz (Standard product, (A) grade product) / 2 to 8 MHz ((A2) grade product)
    - High-speed internal oscillator: 8 MHz ±3% (-10 to +70°C), 8 MHz ±5% (Standard product, (A) grade product: -40 to +85°C, (A2)grade product: -40 to +125°C)
    - Low-speed internal oscillator 240 kHz (TYP.) ... Watchdog timer, timer clock in intermittent operation
  • I/O ports: 14 (CMOS I/O: 13, CMOS input: 1)
  • Timer: 3 channels
    - 16-bit timer/event counter: 1 channel ... Timer output x 1, capture input x 2
    - 8-bit timer: 1 channel ... PWM output x 1
    - Watchdog timer: 1 channel ... Operable with low-speed internal oscillation clock
  • On-chip power-on-clear (POC) circuit (A reset is automatically generated when the voltage drops to 2.1 V (TYP.) or below)
  • On-chip low voltage detector (LVI) circuit (An interrupt/reset (selectable) is generated when the detection voltage is reached)
    - Detection voltage: Selectable from ten levels between 2.35 and 4.3 V
  • Single-power-supply flash memory
    - Flash self programming enabled
    - Software protection function: Protected from outside party copying (no flash reading command)
    - Time required for writing by dedicated flash memory programmer: Approximately 3 seconds (4 KB)
    - Flash programming on mass production lines supported
  • 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
  • Operating temperature range:
    - Standard product, (A) grade product: TA = -40 to +85°C
    - (A2) grade product: TA = -40 to +125°C
