Z8F011APH020SC Equivalent & Substitute Parts

Part Overview

The Z8F011APH020SC is an eZ8 Encore!® XP® 8-bit microcontroller manufactured by Zilog, featuring 1KB FLASH program memory, 256 bytes of RAM, and 16 bytes of EEPROM. This device operates at 20MHz with a supply voltage range of 2.7V to 3.6V and includes integrated peripherals such as UART/USART, PWM, watchdog timer, and brown-out detection. The part is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the Z8F011APH020SC is determined by strict equivalence across the following critical parameters:

• Core processor architecture (eZ8)
• Core size (8-Bit)
• Operating frequency (20MHz)
• Program memory capacity and type (1KB FLASH)
• RAM and EEPROM capacity (256 x 8 and 16 x 8 respectively)
• Supply voltage range (2.7V ~ 3.6V)
• I/O pin count (17)
• Package form factor (20-DIP)
• Peripheral feature set (UART/USART, PWM, WDT, brown-out detection, LVD, POR, LED)
• Operating temperature range (0°C ~ 70°C)

The Z8F011APH020SG2156 meets all these criteria and is therefore a direct functional equivalent. Differences in product status, packaging format (tube vs. standard), and RoHS compliance do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Z8F011APH020SG2156 is the direct substitute for the obsolete Z8F011APH020SC. Both parts share identical electrical specifications, memory configuration, peripheral feature set, and package dimensions. The primary distinction is product lifecycle status: the Z8F011APH020SC is obsolete, while the Z8F011APH020SG2156 maintains active production status.

For new designs or system replacements, the Z8F011APH020SG2156 is the appropriate selection. This part also provides improved compliance posture, meeting ROHS3 requirements compared to the non-compliant status of the original part. Both parts maintain equivalent REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Are Z8F011APH020SC and Z8F011APH020SG2156 pin-compatible?

A: Yes. Both parts use the 20-DIP package with identical pin assignments, I/O count (17), and peripheral connectivity. Direct socket substitution is supported.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Can I use Z8F011APH020SG2156 in existing designs built for Z8F011APH020SC?

A: Yes. The substitute part maintains full functional equivalence across all electrical parameters, memory configuration, operating frequency, supply voltage range, and peripheral features. No design modifications are required.

Q: Does the packaging format difference (tube vs. standard) affect compatibility?

A: No. Packaging format refers only to how components are supplied and does not affect electrical or mechanical compatibility. The actual component package remains 20-DIP in both cases.

Q: Are there any compliance considerations when switching to Z8F011APH020SG2156?

A: The Z8F011APH020SG2156 provides improved compliance with ROHS3 standards. Both parts maintain equivalent REACH and ECCN classifications. Compliance requirements should be evaluated based on your specific application and regulatory environment.
