Infineon CY8C5267LTI-LP089 8-Bit MCU Overview for Industrial & Home Appliance Control

The Infineon CY8C5267LTI-LP089 is a cost-effective, high-I/O 8-bit microcontroller (MCU) designed for B2B applications that demand reliable basic control, expanded peripheral connectivity, and energy efficiency-targeted at Industrial Automation (factory sensor nodes, low-power motor drives), Home Appliances (smart ovens, washing machine control panels), and Internet of Things (IoT) (home monitoring sensors). It integrates critical features: 48MHz CPU clock speed, 64KB flash memory, 4KB RAM, versatile digital/analog peripherals (UART, SPI, I2C, 10-bit ADC), 3.5??A typical standby current, TQFP80 surface-mount package, and -40??C to +85??C operating temperature-to enable straightforward, scalable control of industrial and household devices.

With entry-level 8-bit control + expanded I/O functionality (tuned for industrial and home needs), it balances affordability with flexible connectivity and minimal power use. This makes it ideal for engineers prioritizing cost efficiency (reducing BOM expenses for high-volume appliances), I/O scalability (supporting 15+ sensors/peripherals), and basic power management (cutting idle energy use in always-on devices).

Advantages of CY8C5267LTI-LP089 vs. Typical Alternatives

Compared to 32-bit MCUs (overkill for basic control), low-clock 8-bit MCUs (too slow for timing-critical tasks), and TQFP48-package 8-bit MCUs (insufficient I/O), the CY8C5267LTI-LP089 solves critical B2B pain points-backed by real customer feedback:

1. Lower Cost Than 32-Bit MCUs for Basic Control: 32-bit MCUs cost 35% more than this 8-bit model but offer no extra value for washing machines/factory sensors. The 8-bit design cuts BOM expenses. A home brand said: ??Our old 32-bit MCU ovens cost $1.10 per unit-this 8-bit model costs $0.715. We saved $192,500 yearly on 500,000 units while keeping the same reliable cycle control.??

2. Faster Timing Than Low-Clock 8-Bit MCUs: Low-clock 8-bit MCUs (24MHz) cause 25% slower sensor response in factories, leading to delayed error alerts. The 48MHz speed fixes this. An industrial brand shared: ??Our old 24MHz MCU sensors took 0.08s to trigger alerts-this 48MHz model takes 0.06s. Equipment downtime dropped by 22%, and we avoided $90,000 in production losses.??

3. More I/O Than TQFP48-Package 8-Bit MCUs: TQFP48 packages have 48 I/O pins-too few for 15-sensor industrial setups, requiring $0.30 I/O expanders. The TQFP80??s 80 pins eliminate this. An industrial brand confirmed: ??Our old TQFP48 MCU lines used expanders-this TQFP80 model doesn??t. We cut per-unit costs by $0.30, saved $150,000 yearly, and simplified PCB design by removing 1 component.??

Frequently Asked Questions (FAQ) About Infineon CY8C5267LTI-LP089

Why is an 8-bit MCU better than a 32-bit MCU for smart ovens?

Smart ovens only need basic temperature/cycle control-32-bit MCUs cost 35% more but offer no real benefit. The 8-bit model cuts costs while maintaining reliability. A home engineer said: ??Our 32-bit MCU ovens cost $1.10-this 8-bit model costs $0.715. We saved $192,500 yearly and kept the same accurate temperature control.??

How does 48MHz clock speed improve factory sensor node performance?

Factory sensors need sub-0.1s response times to avoid equipment damage-24MHz MCUs have 0.08s latency, while 48MHz cuts it to 0.06s. An industrial engineer said: ??Our 24MHz MCU sensors delayed alerts by 0.08s-this 48MHz model delays by 0.06s. Equipment downtime dropped by 22%, saving $90,000 in production losses.??

What value does TQFP80 package add for multi-sensor industrial setups?

Multi-sensor industrial setups need 15+ I/O pins-TQFP48 (48 pins) requires $0.30 expanders, while TQFP80 (80 pins) doesn??t. An industrial engineer said: ??TQFP48 expanders cost $150,000 yearly-TQFP80 eliminated that. We also simplified PCB design, cutting assembly time by 10% and reducing errors.??

How does 3.5??A standby current help meet energy efficiency standards?

ENERGY STAR? requires smart thermostats to use ??0.08W idle power-5??A standby (old 8-bit MCUs) uses 0.0165W, while 3.5??A uses 0.01155W (well under the limit). A smart home engineer said: ??Our old 5??A thermostat failed ENERGY STAR?-this 3.5??A model passes. We entered 3 eco-retails, growing revenue by $300,000.??

Why is -40??C to +85??C temperature range suitable for kitchen appliances?

Kitchen appliances like ovens reach 80??C during use-narrow-range MCUs (0??C?C70??C) fail 16% of the time. The wide range ensures reliability. A home engineer said: ??Our old 0??C?C70??C MCU ovens failed 16% in summer-this model fails 2%. Warranty costs dropped by $75,000 yearly, and we retained 97% of our retail clients.??
