Zilog’s High Temperature Masked ROM Z86C08 MCU is suitable for applications that require a general-purpose MCU to operate at sustained elevated temperatures. Unlike Flash-based MCUs that are guaranteed to operate at 150°C for only 40 to 310 days, the High Temperature Z86C08 MCU can operate at a prolonged temperature of 150°C for many years without experiencing program memory data retention issues.
