R5F11EA8ASP#70

Microcontrollers Overview

The R5F11EA8ASP#70 is a 16-bit microcontroller belonging to the RL78/G1E series, manufactured by Renesas Electronics. It features an integrated 128 kB flash memory and 8 kB RAM within a 20-pin LSSOP package. The device operates at a maximum clock frequency of 32 MHz and supports a supply voltage range from 1.8 V to 5.5 V. Designed for industrial environments, it functions reliably across a temperature range of -40°C to +85°C.

Microcontrollers Feature Summary

• Integrates high-density non-volatile memory with 128 kB flash and 8 kB RAM for complex application storage.
• Supports extended supply voltage ranges up to 5.5 V for robust operation in varied power conditions.
• Includes hardware security mechanisms such as illegal operation detection to ensure system integrity.

Microcontrollers Applications

• Industrial control systems requiring secure data processing
• Consumer appliances with extended voltage tolerance needs
• Embedded sensor interfaces in harsh environmental conditions

Microcontrollers Procurement Notes

Verify the specific suffix #70 against official Renesas documentation to confirm the tray packaging configuration. Ensure that the 20-pin LSSOP footprint matches your PCB layout requirements. Confirm moisture sensitivity level handling procedures are followed during assembly to prevent damage.

Microcontrollers Selection Notes

Select this component when a balance of moderate code capacity and wide voltage input is required. The 32 MHz performance suits applications needing efficient instruction execution without excessive power consumption. Consider the 20-pin form factor for space-constrained designs needing sufficient I/O lines.

Microcontrollers Part Context

This part belongs to the RL78/G1E family, which targets cost-sensitive yet feature-rich embedded applications. The series emphasizes low power consumption alongside adequate processing power for general-purpose control tasks. It complements other RL78 variants offering different memory sizes or pin counts.

Microcontrollers Replacement Considerations

Consult the RL78/G1E group user manual for direct pin-compatible alternatives within the same series. Verify electrical characteristics and memory configurations match before substituting with other Renesas MCU models.
