9 / 40 page  2000 Feb 21 9 Philips Semiconductors Product specification Multiprotocol IC Card coupler TDA8006 FUNCTIONAL DESCRIPTION Microcontroller The microcontroller is an 80C52 with 16 kbytes of ROM, 256 byte RAM, timers 0, 1, 2 , and 5 I/O ports (port P0: open-drain; ports P1 to P3: weak pull-up). Port P4 is identical to 83CE560, except that precharge circuits ensure fast rise times at end of read mode (transition times <0.5 µs). The ROM code content can be tested by signature to avoid reading it out after masking; for security bit option, see Table 12. The CPU, timers 0 and 1, serial UART, parallel I/O ports, 256 byte RAM, 16 kbyte ROM and external bus are conventional C51 family library elements. Timer 2 is a conventional C52 element (interrupt enable bit ET2: bit 3 in register IEN1 at byte address E8H and interrupt priority bit PT2: bit 3 in register IP1 at byte address F8H. Register PCON has an added feature: PCON.5 = RFI (reduced Radio Frequency Interference bit). When set to logic 1, pin ALE cannot be toggled. ALE clears on RESET. If access is required to the external data memory via MOVX instructions (see Table 1), set bit PCON.6 = ARD in the PCON register to logic 1. For further information, please refer to the published specification of the 83CE560 in “Data Handbook IC20; 80C51-Based 8-Bit Microcontrollers”. Ports P40 to P47, INT0 and P12 to P17 are used internally for controlling the smart card interface and the other peripherals. Ports P34 and P35 are used to control the auxiliary contacts C4 and C8. The list of differences given in Table 1 may help the software developer of the dedicated emulation board for the TDA8006 or other devices.
