The μPD750108 is one of the 75XL series 4-bit single-chip microcontrollers, which provide data processing capability equal to that of an 8-bit microcontroller. The μPD750108 is produced by replacing the main system clock oscillator of the μPD750008 with an RC oscillator, enabling operation at a relatively low voltage of 1.8 V. In addition, it is best suited to applications using batteries. The μPD750108(A) has a higher reliability than the μPD750108. A built-in one-time PROM product, μPD75P0116, is also available. It is suitable for small-scale production and evaluation of application systems.

FEATURES

? Built-in RC oscillator

? Enables the immediate start of processing after the

release of standby mode

? Capable of low-voltage operation: VDD = 1.8 to 5.5 V

? Internal memory

Program memory (ROM)

: 4,096 × 8 bits (μPD750104 and μPD750104(A))

: 6,144 × 8 bits (μPD750106 and μPD750106(A))

: 8,192 × 8 bits (μPD750108 and μPD750108(A))

Data memory (RAM)

: 512 × 4 bits

? Function for specifying the instruction execution time (useful for saving power)

4 μs, 8 μs, 16 μs, 64 μs (when operating at 1.0 MHz)

2 μs, 4 μs, 8 μs, 32 μs (when operating at 2.0 MHz)

122 μs (when operating at 32.768 kHz)

? Enhanced timer function (4 channels)

? Can be easily substituted for the μPD750008 because this product succeeds to the functions and instructions of the μPD750008.

APPLICATIONS

? μPD750104, μPD750106, and μPD750108 Cameras, meters, and pagers

? μPD750104(A), μPD750106(A), and μPD750108(A) Electrical equipment for automobiles
