Z86E0812HSG1866

Microcontrollers Overview

The Z86E0812HSG1866 is an 8-bit microcontroller based on the Z8 core, featuring 2 kB of OTP program memory and 125 bytes of data RAM. It operates with a maximum clock frequency of 12 MHz and supports a supply voltage range of 4.5 V to 5.5 V. The device is housed in a 20-SSOP package with 14 I/O lines and includes two timers/counters. It lacks an ADC and functions within a temperature range of 0°C to +70°C.

Microcontrollers Feature Summary

• Integrates a Z8 8-bit processor core for embedded control tasks
• Utilizes one-time programmable (OTP) memory for code storage
• Includes built-in power-on reset and watchdog timer peripherals

Microcontrollers Applications

• General-purpose embedded control systems
• Industrial automation logic controllers
• Consumer appliance management units

Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability. Confirm RoHS compliance status and check for specific packaging variations such as tube quantities. Ensure compatibility with existing PCB footprints for the 20-SSOP package before procurement.

Microcontrollers Selection Notes

Select this component when an 8-bit architecture with OTP memory is required for cost-sensitive applications. Consider the 12 MHz speed limit and 14 I/O count against project requirements. Evaluate the 4.5 V to 5.5 V operating voltage range to ensure alignment with system power rails.

Microcontrollers Part Context

This part belongs to the Z86E08x series of 8-bit microcontrollers manufactured by Zilog. It shares architectural similarities with other members of the family but differs in memory size and package type. The Z8 core provides a balance of processing capability and peripheral integration suitable for standalone control applications.

Microcontrollers Replacement Considerations

Check for obsolete status notifications from the manufacturer. Verify pin-to-pin compatibility if substituting with other Z86E08xx variants. Confirm that alternative sources offer equivalent OTP programming capabilities and package dimensions.
