Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLGSP#30 | RL78/G13-based; lower Flash (64 KB), higher code efficiency (1.08 DMIPS/MHz), no hardware LIN | Targeted at cost-sensitive consumer appliances where LIN is not required | Select when prioritizing ultra-low power (0.52 μA STOP mode) over analog precision or legacy peripheral compatibility |
| MB95F622KPMC-GSE1 | Fujitsu FM3-based; 128 KB Flash, 16 KB RAM, but lacks integrated RTC and has different ADC architecture (10-bit SAR) | Suitable for industrial HMI panels requiring larger RAM but less demanding on timing-critical analog capture | Choose when needing larger RAM buffer for graphics rendering and accepting trade-off in ADC resolution and calendar functionality |

FAQ
What is the maximum operating frequency of the UPD78F1168AGC-UEU-E2-AX?
The UPD78F1168AGC-UEU-E2-AX supports a maximum CPU clock frequency of 20 MHz when powered within its specified supply voltage range (2.7–5.5 V). This frequency is achieved using an external crystal oscillator or ceramic resonator connected to the X1/X2 pins, or via internal high-speed RC oscillator with optional trimming. The actual achievable frequency depends on ambient temperature and supply stability, as confirmed in Renesas Electrical Characteristics table (U17894EJ9V0UD, Section 5.2).
Does the UPD78F1168AGC-UEU-E2-AX include a hardware real-time clock (RTC)?
Yes, the UPD78F1168AGC-UEU-E2-AX integrates a full-featured RTC module supporting calendar functions (year/month/day/hour/minute/second), alarm interrupts, and 32.768 kHz crystal input. It operates independently in STOP mode and retains timekeeping during low-power states, with register access via dedicated SFRs. This RTC is documented in Chapter 15 of the UPD78F1168AGC-UEU-E2-AX User's Manual U17894EJ9V0UD.
What is the Flash memory endurance specification for the UPD78F1168AGC-UEU-E2-AX?
The UPD78F1168AGC-UEU-E2-AX guarantees 100,000 write/erase cycles for its 128 KB on-chip Flash memory, with data retention of 10 years at 85°C. This endurance applies to both main program memory and the dedicated 256-byte data flash area. Endurance testing follows JEDEC JESD22-A117 standards, and wear-leveling must be implemented in firmware for applications requiring frequent updates.
Can the UPD78F1168AGC-UEU-E2-AX operate from a 3.3 V supply only?
Yes, the UPD78F1168AGC-UEU-E2-AX operates reliably across 2.7–5.5 V, making 3.3 V a fully supported nominal supply. At 3.3 V, it achieves full 20 MHz operation and maintains all peripheral functionality, including ADC accuracy and UART baud rate stability. The internal voltage regulator (controlled via REGC pin) ensures consistent core voltage regardless of input variation, as verified in Renesas DC Characteristics (U17894EJ9V0UD, Table 5.1).
Is the UPD78F1168AGC-UEU-E2-AX qualified for automotive applications?
No, the UPD78F1168AGC-UEU-E2-AX is rated for Standard quality grade per Renesas classification, intended for computers, office equipment, industrial robots, and consumer appliances - not automotive or safety-critical systems. It does not meet AEC-Q100 requirements, lacks extended temperature screening (−40°C to +125°C), and has no automotive-specific qualification documentation. For automotive use, Renesas recommends RL78/F1x or RH850 families instead of the 78K0R/KG3 series.
