Features, Applications

Four-Bit CMOS Microcontrollers for Small-Scale Control Applications

The LC651154N/F/L and the LC651152N/F/L are the small-scale control application versions of Sanyo's LC6500 series of 4-bit single-chip CMOS microcontrollers, and feature the same basic architecture and instruction set. These microcontrollers include 8input 8-bit A/D converter and are appropriate for use in a wide range of applications, from applications with a small number of circuits and controls that were previously implemented in standard logic to applications with a larger scale such as home appliances, automotive equipment, communications equipment, office equipment, and audio equipment such as decks and players. Also note that since these ICs provide the same basic functions (certain functions and specifications do differ) as, and are pin compatible with the earlier LC651104N/F/L and LC651102N/F/L, they can replace those ICs in most cases. All ports: Are I/O ports I/O voltage handling capacity: 15 V (maximum) (Open-drain specification D, E, and F ports only) Output current: 20 mA (maximum) sink current (Are capable of directly driving an LED.) Support options to match application system specifications A. Open-drain output, internal pull-up resistor specification: All ports, in bit units B. Output level at reset specification: Ports C and D can be specified go to the high or low level in 4-bit units. Interrupt function Timer interrupts through an interrupt vector (Can be tested under program control) INT pin and serial I/O full/empty interrupts through an interrupt vector (Can be tested under program control) Stack levels: 8 (Shared with the interrupt system.) Timers: 4-bit variable prescaler and 8-bit programmable timers Clock oscillator options that match a wide range of system specifications Oscillator circuit options: Two-pin RC oscillator (N and L versions) Two-pin ceramic oscillator (N, F, and L versions) Clock divider circuit options: No divider, built-in divide-by-3, built-in divide-by-4 (N and L versions) Continuous square wave output (with a period 64 times the cycle time) A/D converter (successive approximation) 8-bit precision with 8 input channels Watchdog timer
