1 / 66 page ![]() The µPD754202 is a member of the 75XL Series of 4-bit single-chip microcontrollers that enable data processing equivalent to that of an 8-bit microcontroller. It features expanded CPU functions compared to the 75X Series and enables high-speed, low-voltage operation at 1.8 V, making it suitable for battery-driven applications. The µPD754202(A) is a higher-reliability product compared to the µPD754202. Detailed function descriptions, etc., are provided in the following user’s manual. Be sure to read it when designing. µPD754202 User’s Manual: U11132E FEATURES • Key return reset function for keyless entry • Low-voltage operation: VDD = 1.8 to 6.0 V • On-chip memory • Program memory (ROM): 2048 × 8 bits • Data memory (RAM) : 128 × 4 bits • Variable instruction execution time useful for high-speed operation and power save • 0.95, 1.91, 3.81, 15.3 µs (at 4.19-MHz operation) • 0.67, 1.33, 2.67, 10.7 µs (at 6.0-MHz operation) • Compact package (20-pin plastic shrink SOP (300 mil, 0.65-mm pitch)) APPLICATIONS Automotive electronics such as keyless entry units The µPD754202 and µPD754202(A) have different quality grades. Unless otherwise specified, descriptions in this data sheet apply to the µPD754202.
