Industrial temperature range and through-hole package — fit for prototyping and harsh environments
The 20-pin PDIP (0.300" wide, 7.62 mm pitch) through-hole package makes this part a natural choice for breadboard prototyping, low-volume production, or applications requiring robust solder joints in high-vibration settings. It is not a surface-mount part — plan for a through-hole soldering step or use a DIP socket.
2 KB Flash and 256 bytes RAM — budgeting the firmware
The 2 KB Flash program memory (2K x 8) and 256 x 8 bytes of RAM are the major constraints for firmware engineers. Expect to fit a small scheduler, a few sensor drivers, and a serial protocol stack, but there is no room for a full RTOS or large lookup tables. The Flash is in-system programmable via the JTAG/SBW interface, supporting field updates if the bootloader fits. RAM at 256 bytes means the stack depth, global variables, and any DMA buffers must be carefully sized. For data-logging or buffered communication, consider external serial EEPROM or FRAM — the I²C/SPI peripherals make that straightforward.
