6 / 20 page 1998 Apr 20 6 Philips Semiconductors Product specification Telecom microcontroller PCF84C81A 8 ROM MASK OPTIONS 9 HANDLING Inputs and outputs are protected against electrostatic discharge in normal handling. However, it is good practice to take normal precautions appropriate to handling MOS devices. See “Data Handbook IC14, Section: Handling MOS devices”. 10 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134). ROM CODE OPTION Program/data Any mix of instructions and data up to ROM size of 8 kbytes. Port Output P0.0 to P0.7 standard open-drain push-pull P1.0 to P1.7 standard open-drain push-pull P2.0 to P2.2 standard open-drain push-pull SDA/P2.3 − open-drain − Port State after reset P0.0 to P0.7 set reset − P1.0 to P1.7 set reset − P2.0 to P2.2 set reset − SDA/P2.3 set −− Oscillator Transconductance LOW (gmL) MEDIUM (gmM) HIGH (gmH) SYMBOL PARAMETER MIN.
