Detailed Description for DS80C323-MCD+
Product Overview
The DS80C323-MCD+ from Analog Devices Inc./Maxim Integrated is an 8-bit 8051 microcontroller in a through-hole 40-DIP package. It is specified for operation at 18 MHz and uses an external oscillator. The device has a ROMless program memory architecture, 256 x 8 bits of RAM, and 32 I/O pins. Connectivity includes EBI/EMI, SIO, and UART/USART interfaces. Peripheral functions include power-fail reset and a watchdog timer. The supply voltage range is 2.7 V to 5.5 V, and the operating temperature range is 0°C to 70°C.
Key Features
- 8-bit 8051 core specified for 18 MHz operation
- ROMless program memory architecture requiring external program storage
- 256 x 8 bits of RAM and 32 I/O pins
- EBI/EMI, SIO, and UART/USART connectivity interfaces
- Power-fail reset and watchdog timer peripherals
- 2.7 V to 5.5 V supply range and 0°C to 70°C operating temperature
- 40-PDIP through-hole package, 40-DIP (0.600 in, 15.24 mm)
Applications
- Embedded control boards that require external program memory and serial communication
- Instruments or measurement devices using external bus interfaces for memory or peripheral expansion
- Through-hole prototype or development systems based on the 8051 instruction set
- Systems using power-fail reset and watchdog timer for basic supervisory functions
Design & Procurement Notes
Because the DS80C323-MCD+ is ROMless, the system design must provide external program memory and use the external bus interface for program access. An external oscillator is required for clocking, so the oscillator selection should be compatible with the 18 MHz specification. The 2.7 V to 5.5 V supply range should be checked against the board power rails, and the 0°C to 70°C temperature range should be reviewed for the intended operating environment. The 32 I/O pins, EBI/EMI, SIO, UART/USART interfaces, power-fail reset, and watchdog timer should be mapped to the required firmware and hardware functions. The 40-PDIP through-hole package supports through-hole PCB assembly.
