37 / 64 page  Philips Semiconductors Preliminary data 87LPC768 Low power, low price, low pin count (20 pin) microcontroller with 4 kB OTP 8-bit A/D, Pulse Width Modulator 2001 Aug 06 35 Low Voltage EPROM Operation The EPROM array contains some analog circuits that are not required when VDD is less than 4 V, but are required for a VDD greater than 4 V. The LPEP bit (AUXR.4), when set by software, will power down these analog circuits resulting in a reduced supply current. LPEP is cleared only by power-on reset, so it may be set ONLY for applications that always operate with VDD less than 4 V. Reset The 87LPC768 has an active low reset input when configured for an external reset. A fully internal reset may also be configured which provides a reset when power is initially applied to the device. The watchdog timer can act as an oscillator fail detect because it uses an independent, fully on-chip oscillator. The external reset input is disabled, and fully internal reset generation enabled, by programming the RPD bit in the EPROM configuration register UCFG1 to 0. EPROM configuration is described in the section EPROM Characteristics SU01391 87LPC768 87LPC768 VDD 8.2 k W 10 mF RST RST 2.2 mF Figure 23.
