Low-pin-count (78K0S/Kx1+) microcontrollers are low-end Microcontrollers.
The flash only products include OSC and comprehensive development tools.

Key Features:

Operating 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 8 KB flash memory
RAM capacities: 128 bytes to 256 bytes
Package: 10 pin plastic SSOP, 16-pin Plastic SSOP, SDIP and WLBGA package, 20 pin plastic SSOP and plastic SDIP package, 30-pin Plastic SSOP and 32-pin SDIP 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:

  • 8 : 10-pin products
  • 14 (CMOS I/O: 13, CMOS input: 1) : 16-pin products
  • 17 (CMOS I/O: 15, CMOS input: 1, CMOS output: 1) : 20-pin products
  • 26 (CMOS I/O: 24, CMOS input: 1, CMOS output: 1) : 30-pin products

Timer: 3/4 channels

  • 16-bit timer/event counter: 1 channel Timer output x 1, capture input x 2
  • 8-bit timer: 2 channels PWM output x 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: 0/4 channels
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 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)

* 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)

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

Key Applications:

  • Home appliances, Home audio systems, Digital cameras etc.
