C511 / C513

The C511, C511A, C513, C513A, 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 first four versions contains a non-volatile read-only (ROM) program memory. 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 members of the microcontroller family differ in functionality according table 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. The functionality of the C513A-H is a superset of all ROM versions of the C511/C513 family.

I/O Port 1

is a bidirectional I/O port with internal pull-up resistors. Port 1 pins that have 1s written to them are pulled high by the internal pullup resistors, and in that state can be used as inputs. As inputs, port 1 pins being externally pulled low will source current (

, in the DC characteristics) because of the internal pullup resistors. Port 1 also contains the timer 2 and SSC pins as secondary function. In general the output latch corresponding to a secondary function must be programmed to a one (1) for that function to operate. For the outputs of the SSC (SCLK, STO) special circuitry is implemented, providing true push-pull capability. The STO output in addition will have true tristate capability. When used for SSC inputs, the pull-up resistors will be switched off and the inputs will float (high ohmic inputs).

The alternate functions are assigned to port 1, as follows:

P1.0 T2 Input to counter 2

I/O Port 3

is a bidirectional I/O port with internal pull-up resistors. Port 3 pins that have 1s written to them are pulled high by the internal pullup resistors, and in that state can be used as inputs. As inputs, port 3 pins being externally pulled low will source current (I

, in the DC characteristics) because of the internal pullup resistors. Port 3 also contains the interrupt, timer, serial port and external memory strobe pins that are used by various options. The output latch corresponding to a secondary function must be programmed to a one (1) for that function to operate.

The secondary functions are assigned to the pins of port 3 as follows:

XTAL1 21 15 – XTAL1

Input to the inverting oscillator amplifier and input to the internal clock generator circuits. To drive the device from an external clock source, XTAL1 should be driven, while XTAL2 is left unconnected. There are no requirements on the duty cycle of the external clock signal, since the input to the internal clocking circuitry is divided down by a divide-by-two flip-flop. Minimum and maximum high and low times as well as rise/fall times specified in the AC characteristics must be observed.

P2.0-P2.7 24-31 18-25 I/O Port 2

is a bidirectional I/O port with internal pullup resistors. Port 2 pins that have 1s written to them are pulled high by the internal pullup resistors, and in that state can be used as inputs. As inputs, port 2 pins being externally pulled low will source current (

, in the DC characteristics) because of the internal pullup resistors. Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that use 16-bit addresses (MOVX @DPTR). In this application it uses strong internal pullup resistors when issuing 1s. During accesses to external data memory that use 8-bit addresses (MOVX @Ri), port 2 issues the contents of the P2 special function register.

32 26 O The Program Store

Enable output is a control signal that enables the external program memory to the bus during external fetch operations. It is activated every six oscillator periodes except during external data memory accesses. Remains high during internal program execution.

ALE 33 27 O The Address Latch Enable

output is used for latching the low-byte of the address into external memory during normal operation. It is activated every six oscillator periodes except during an external data memory access. If no external memory is used, the ALE signal generation can be inhibited, reducing system RFI, by clearing register bit EALE in the SYSCON register.

35 29 I External Access Enable

When held at high level, instructions are fetched from the internal ROM when the PC is less than the size of the internal ROM : C511 0A00

C513 2000

C513A/A-H 3000

When held at low level, the microcontroller fetches all instructions from external program memory.

P0.0-P0.7 43-36 37-30 I/O Port 0

is an 8-bit open-drain bidirectional I/O port. Port 0 pins that have 1s written to them float, and in that state can be used as high-impendance inputs. Port 0 is also the multiplexed low-order address and data bus during accesses to external program or data memory. In this application it uses strong internal pullup transistors when issuing 1s. External pullup resistors are required during program verification.

This input is used to latch address information at AD0-7. The trailing edge of PALE is used to latch the register addresses. Each read or write access in programming mode must be initiated by a PALE high pulse.
