LC651202L

Ordering number : EN*5190 CMOS LSI LC651204N/F/L, LC651202N/F/L 4-Bit Single-Chip Microcontrollers for Small-Scale Control Applications Preliminary Overview The LC651204N/F/L and LC651202N/F/L are small-scale application microcontroller products in Sanyo's LC6500 series of 4-bit single-chip CMOS microcontrollers, and as such they fully support the basic architecture and instruction set of that series. These microcontrollers are provided in a 30-pin package and include 2 kilobytes (KB) and 4 KB of on-chip ROM. These products are appropriate for use in a wide range of applications, from applications that use a small number of controls and circuits that were previously implemented in standard logic to larger scale applications including audio equipment such as decks and players, office equipment, communications equipment, automotive equipment, and home appliances. Except for the lack of an A/D converter, these microcontrollers provide the same functionality as the LC651104, 02N/F/L. Specification of the output level at reset: Can be specified to be high or low for ports C and D in port units. Interrupt functions — Timer overflow vector interrupt (The interrupt state can be tested by the CPU.) — Vector interrupts initiated by the INT pin or full/empty states of the serial I/O circuit. (The interrupt state can be tested by the CPU.) Stack levels: 8 levels (shared with interrupts) Timers: 4-bit prescaler plus 8-bit programmable timers Clock oscillator options to match applicati...
