UPD78F9200MA-CAC-A Equivalent & Substitute Parts

Part Overview

The UPD78F9200MA-CAC-A is an 8-bit microcontroller from Renesas Electronics Corporation's 78K0S/Kx1+ series, featuring 1KB FLASH program memory and 128 bytes of RAM. This device is classified as obsolete, making identification of suitable alternatives essential for ongoing production and maintenance applications. The 10-LSSOP surface mount package and integrated peripherals including LVD, POR, PWM, and WDT support embedded control applications requiring low-power operation across the 2V to 5.5V supply range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPD78F9200MA-CAC-A is determined by the following critical parameters:

Electrical Compatibility:

• Program Memory Size: 1KB (1K x 8) FLASH
• RAM Size: 128 x 8
• Voltage Supply Range: 2V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C

Physical Compatibility:

• Package Type: 10-LSSOP
• Mounting Type: Surface Mount
• Pin Count: 10 pins

Functional Compatibility:

• Integrated Peripherals: LVD, POR, PWM, WDT
• Data Converter: A/D capability
• Oscillator Type: Internal

The R5F10Y14ASP#V0 qualifies as a substitute based on matching program memory capacity, RAM size, supply voltage range, operating temperature, package type, and core peripheral set. Differences in core processor architecture (RL78 vs. 78K0S), core size (16-Bit vs. 8-Bit), and maximum speed (20MHz vs. 10MHz) do not preclude substitution when memory and I/O requirements are met.

Parameter Comparison

Engineering Selection Recommendations

Both the UPD78F9200MA-CAC-A and R5F10Y14ASP#V0 are classified as end-of-life products. The UPD78F9200MA-CAC-A is marked as Obsolete, while the R5F10Y14ASP#V0 is designated Not For New Designs. Both devices maintain ROHS3 compliance and identical MSL ratings, supporting equivalent handling and storage requirements.

The R5F10Y14ASP#V0 provides enhanced functionality through additional DMA capability and dual-mode A/D conversion (8/10-bit), while maintaining identical memory capacity and supply specifications. The 10-LSSOP package footprint differs slightly in width (4.40mm vs. 5.72mm), requiring PCB layout verification for mechanical compatibility.

Selection between these parts should prioritize application memory requirements, I/O pin count needs, and PCB layout constraints. Both devices support the specified operating temperature and voltage ranges without modification to power supply or thermal management designs.

Frequently Asked Questions (FAQ)

Q: Can the R5F10Y14ASP#V0 directly replace the UPD78F9200MA-CAC-A in existing designs?

A: Direct replacement requires verification of three factors: (1) PCB footprint compatibility, as the 10-LSSOP package width differs by 1.32mm; (2) firmware compatibility, as the RL78 core architecture differs from the 78K0S core; (3) I/O pin assignment alignment, as the R5F10Y14ASP#V0 provides 6 I/O pins versus 7 on the original part.

Q: What are the memory specifications that determine substitution eligibility?

A: Both parts feature identical program memory (1KB FLASH) and RAM (128 x 8 bytes). These matching specifications ensure equivalent data storage capacity for applications designed around the UPD78F9200MA-CAC-A memory footprint.

Q: Are there supply voltage differences between these parts?

A: No. Both the UPD78F9200MA-CAC-A and R5F10Y14ASP#V0 operate across the 2V to 5.5V supply range and maintain identical -40°C to 85°C operating temperature specifications.

Q: What is the significance of the product status designations?

A: The UPD78F9200MA-CAC-A is classified as Obsolete, indicating discontinued production and limited availability. The R5F10Y14ASP#V0 is designated Not For New Designs, indicating end-of-life status with restricted use in new product development. Both statuses reflect Renesas Electronics Corporation's product lifecycle decisions.

Q: How do the peripheral sets differ between these microcontrollers?

A: The UPD78F9200MA-CAC-A includes LVD, POR, PWM, and WDT peripherals. The R5F10Y14ASP#V0 includes the same peripherals plus DMA capability. The R5F10Y14ASP#V0 also supports expanded connectivity options (CSI, I2C, LINbus, UART/USART) not specified for the original part.

Q: What packaging considerations apply to substitution?

A: Both parts use 10-LSSOP surface mount packages. The physical width differs (5.72mm vs. 4.40mm), requiring PCB layout review. Both maintain identical MSL 3 ratings (168 hours), supporting equivalent moisture control and reflow processing procedures.
