This speed determines instruction-cycle timing for time-critical loops in industrial control, sensor polling, or serial communication tasks. As a ROMless device, all program memory must reside externally — the 256 x 8 on-chip RAM serves register file and scratchpad only. This suits designs where code is stored in external EPROM, flash, or OTP memory, typical in legacy 8051 systems or prototyping. ## Industrial temperature grade and 5V supply rail The 40-pin DIP package (0.600-inch width, 15.24 mm row spacing) is through-hole mounted — suitable for socketed prototyping, breadboard bring-up, or boards where rework access is needed. The supplier device package is 40-PDIP. ## On-chip peripherals and I/O for embedded control Integrated peripherals include a power-fail reset and watchdog timer (WDT) — the WDT provides autonomous system recovery from firmware hangs, critical in unattended or safety-monitored installations. The power-fail reset ensures orderly shutdown on supply brownout. With 32 general-purpose I/O pins, the part can handle parallel sensor arrays, keypad scanning, or relay bank control without external port expanders. ## Active lifecycle and compliance documentation RoHS3 compliant (2011/65/EU + 2015/863), it meets the current environmental directive for EU-market equipment.","metaTitle":"DS80C320-MNG+ 8051 MCU, 25MHz, 40-DIP, Active","metaDescription":"Analog Devices DS80C320-MNG+ 8-bit MCU, 8051 core at 25MHz, ROMless, 256x8 RAM, 40-PDIP, -40°C to +85°C.
