Because the part is ROMless, you must budget for an external parallel flash or EPROM plus an address latch (typically a 74HC373) to hold the program image, adding 2-3 ICs and board area beyond the MCU itself. The 40-pin DIP package (0.600-inch row spacing) is a through-hole footprint — it suits prototyping boards, socketed production, or rework scenarios where a soldered QFP would be harder to replace. ## Peripheral set and voltage requirements On-chip peripherals include a power-fail reset and a watchdog timer (WDT), which together can supervise supply brownouts and code hangs without an external supervisor IC — a cost saving in high-volume embedded control. Connectivity covers EBI/EMI for external memory access, plus SIO and a UART/USART for serial communication with sensors, displays, or host controllers. The 32 general-purpose I/O pins, combined with the external memory interface, give enough headroom for a small keypad-and-LCD panel or a handful of relay drivers and sensor inputs. ## Sourcing and compliance RoHS3 compliant (2011/65/EU + 2015/863), with no lead, mercury, cadmium, or other restricted substances above threshold levels in the homogeneous material.","metaTitle":"DS80C320-MCG+ 8-bit MCU, 25MHz, 40-DIP, Analog Devices","metaDescription":"DS80C320-MCG+ 8-bit 8051 MCU, 25MHz, 256x8 RAM, ROMless, 40-PDIP.
