78K0S/KA1+ Microcontrollers

Features

  • Operating Voltage : 2.0 to 5.5 V
  • Maximum Operating Frequency 10 MHz
  • Flash ROM
  • 2 to 8 KB Program memory
  • 128 to 256 byte internal RAM
  • 20 pin plastic SSOP and plastic SDIP package
  • 78K0S CPU core
  • Minimum instruction execution time: 0.2 µs (with 10 MHz@4.0 to 5.5 V operation)
  • 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 +80°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: 17 (CMOS I/O: 15, CMOS input: 1, CMOS output: 1)
  • Timer: 4 channels
    - 16-bit timer/event counter: 1 channel … Timer output × 1, capture input × 2
    - 8-bit timer: 2 channel … PWM output × 1
    - Watchdog timer: 1 channel … Operable with low-speed internal oscillation clock
  • Serial interface: UART (LIN (Local Interconnect Network) bus supported) 1 channel
  • 10-bit resolution A/D converter: 4 channels
  • On-chip power-on-clear (POC) circuit (A reset is automatically generated when the voltage drops to 2.1 V ±0.1 Vor below)
  • On-chip low voltage detector (LVI) circuit (An interrupt/reset (selectable) is generated when the detection voltageis 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)
  • 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
  • Assembler and C language supported
  • Enhanced development environment
    - Support for full-function emulator (IECUBE), on-chip debug emulator (MINICUBE2), and simulator
  • Operating temperature range: Standard product, (A) grade product: Ta = −40 to +85°C / (A2) grade product: Ta = −40 to +125°C
