AN339 DIFFERENCES BETWEEN THE C8051F33X AND THE C8051T63X DEVICE FAMILIES
The C8051T63x devices are low-cost, electrically-programmable read-only memory (EPROM) microcontrollers based on the Silicon Laboratories CIP-51 microcontroller core. As with Silicon Laboratories’ C8051F-series Flash-based microcontrollers, the C8051T63x are highly-integrated, mixed-signal devices incorporating communication peripherals as well as analog-to-digital converter (ADC) technology. Also included is the C2 2-wire debugging and programming interface, allowing designers to rapidly develop and debug firmware.
Because the devices in the C8051T63x family cannot be erased, a new device is required for testing every time the firmware changes. This could make the code development process more difficult and time consuming. Fortunately,the features found in the C8051T63x family are closely related to the features of two other Flash-based device families: the C8051F330-5, and the C8051F336-9. The most closely-related of these devices is the C8051F336,which is included on an “emulation daughter card” in the C8051T630-DK. In most cases, the C8051F336 can be used for the entire code development process, and the firmware image will be interchangeable between the two device families. For systems that take advantage of the additional features found in the C8051T63x family, the majority of the firmware can still be developed on the C8051F336 device and then ported to the C8051T63x during the final stages of code development.
This document details the hardware differences between the EPROM and Flash device families and provides some guidelines for using the C8051F336 to develop code for the C8051T63x.
Key Points：
■Although the majority of device features are identical between the C8051F330–5, the C8051F336–9, and the C8051T63x, there are some hardware differences.
■When developing code for the C8051T63x device family, the majority of the code development process can be done on one of the Flash-based counterparts, and the C8051F336 is the closest Flash-based relative.
■Each device family has a set of unique features that are not present on the other families. Recognizing these differences is the key to successfully developing common code (code that works across all families) or code that uses some of the additional features found on the C8051T63x.
