6 / 128 page  Introduction Semiconductor Group 1-1 1 Introduction The C511-R, C511A-R, C513-R, C513A-R, C513A-2R, and C513A-H are members of a family of low cost microcontrollers, which are software compatible with the components of the SAB 8051, SAB 80C51 and C500 families. The five versions with the “-R” extension contain a non-volatile read-only program memory (ROM). The C513A-H is a version with a 12 Kbyte EEPROM instead of ROM. This device can be used for prototype designs which have a demand for reprogrammable on-chip code memory. The microcontroller versions differ in functionality according table 1-1. They offer different ROM sizes, different RAM/XRAM sizes and a different timer/USART configuration. Common to all devices is an advanced SSC serial port, a second synchronous serial interface, which is compatible to the SPI serial bus industry standard. Except the EEPROM size, the functionality of the C513A-H is a superset of all ROM versions of the C511/513 family. In this user manual the microcontroller family is also referenced with the term C511/513 and the ROM versions are referenced without the “-R” extension. If some of the features described are applicable to selected family members only, this will be explicitly stated. Table 1-1 Functionality of the C511/513 MCUs Note: 1) T0 and T1 are the standard 16-bit timer. T2 is the 16-bit timer with autoreload. 2) USART is the Universal Synchronous/Asynchronous Receive/Transmit interface. 3) SSC is the Synchronous Serial Channel (SPI compatible interface). According table 1-1, figure 1-1 to figure 1-4 show the functional units of the members of the C511/ 513 family microcontrollers.
