2 GENERAL DESCRIPTION

This data sheet details the specific properties of the devices referred to. The shared properties of the PCD33xxA family of microcontrollers are described in the

“PCD33xxA family”

data sheet, which should be read in

conjunction with this publication.

• ‘PCA3351C; 52C; 53C’ denotes the types PCA3351C, PCA3352C and PCA3353C. Unless specified, these types will hereafter be referred to collectively as ‘PCA335xC’.

• ‘PCD3351A; 52A; 53A’ denotes the types PCD3351A, PCD3352A, PCD3353A. Unless specified, these types will hereafter be referred to collectively as ‘PCD335xA’.

The PCA335xC and PCD335xA are microcontrollers designed primarily for telephony applications. They include an on-chip generator for dual tone multifrequency (DTMF), modem and musical tones. In addition to dialling, generated frequencies can be made available as square waves for melody generation, providing ringer operation.

The PCA335xC and PCD335xA also incorporate 128 bytes of EEPROM, permitting data storage without battery backup. The EEPROM can be used for storing telephone numbers, particularly for implementing redial functions.

The PCA335xC and PCD335xA can be emulated with the OTP microcontrollers PCD3755A and PCD3755E. See Chapter 14, Table 25.

The instruction set is similar to that of the MAB8048 and is a sub-set of that listed in the

“PCD33xxA family”

data

sheet. The differences between PCA335xC and PCD335xA are

shown in Table 1.

6 FREQUENCY GENERATOR

A versatile frequency generator section is provided (see Fig.4). For normal operation, use a 3.58 MHz quartz crystal or PXE resonator. The frequency generator includes precision circuitry for dual tone multifrequency (DTMF) signals, which is typically used for tone dialling telephone sets.

Theirfrequencies are provided in purely sinusoidalformon the TONE output or as square waves on the port line P1.7/MDY.

The TONE output can alternatively issue twelve modem frequencies for data rates between 300 and 1200 bits/s.

In addition to DTMF and modem frequencies, two octaves of musical scale in steps of semitones are available.

When no tones are generated the TONE output is in 3-state mode.

BIT SYMBOL DESCRIPTION

7to1 − These bits are set to a logic 0.

0 EMO Enable Melody Output. If bit EMO = 0, then P1.7/MDY is a standard port line.

If bit EMO = 1, then P1.7/MDY is the melody output. EMO = 1 does not inhibit the port instructions for P1.7/MDY. Therefore the state of both port line and ﬂip-ﬂop may be read in and the port ﬂip-ﬂop may be written by port instructions. However, the port ﬂip-ﬂop of P1.7/MDY must remain set to avoid conﬂicts between melody and port outputs. When the HGF contents are zero while EMO = 1, P1.7/MDY is in the HIGH state.

6.2 Melody output (P1.7/MDY)

The melody output (P1.7/MDY) is very useful for generating musical notes when a purely sinusoidal signal is not required, such as for ringer applications.

The square wave (duty cycle =12⁄23 or 52%) will include the attenuated harmonics of the base frequency, which is defined by the contents of the HGF register (Table 4). However, even higher frequency notes may be produced since the low-pass filtering on the TONE output is not applied to the P1.7/MDY output. This results in the minimum decimal value x in the HGF register (see equation in Section 6.3) being 2 for the P1.7/MDY output, rather than 60 for the TONE output. A sinusoidal TONE output is produced at the same time as the melody square wave, but due to the filtering, the higher frequency sine waves with x < 60 will not appear at the TONE output.

Since the melody output is shared with P1.7, the port flip-flop of P1.7 has to be set HIGH before using the melodyoutput.Thistoavoidconflictsbetween melody and port outputs. The melody output drive depends on the configuration of port P1.7/MDY, see Chapter 14, Table 26.

6.3 Frequency registers

The two frequency registers HGF and LGF define two frequencies. From these, the digital sine synthesizers together with the Digital-to-Analog Converters (DACs) construct two sine waves. Their amplitudes are precisely scaled according to the bandgap voltage reference. This ensures tone output levels independent of supply voltage and temperature.

The amplitude of the Low Group Frequency sine wave is attenuated by 2 dB compared to the amplitude of the High Group Frequency sine wave.

The two sine waves are summed and then filtered by an on-chip switched capacitor and RC low-pass filters. These guarantee that all DTMF tones generated fulfil the CEPT recommendations with respect to amplitude, frequency deviation, total harmonic distortion and suppression of unwanted frequency components.

The value 00H in a frequency register stops the corresponding digital sine synthesizer. If both frequency registers contain 00H, the whole frequency generator is shut off, resulting in lower power consumption.

Thefrequency of the sinewavegeneratedfrom either HGF or LGF is a function of the decimal value ‘x’ held in the register. The variables are related by the equation:

; where 60 ≤ x ≤ 255 for TONE output.

6.4 DTMF frequencies

Assuming an oscillator frequency f

xtal

= 3.58 MHz, the DTMF standard frequencies can be implemented as shown in Table 7.

The relationships between telephone keyboard symbols, DTMFfrequencypairsandthefrequencyregistercontents are given in Table 8.

6.5 Modem frequencies

Again assuming an oscillator frequency f

= 3.58 MHz, the standard modem frequencies can be implemented as in Table 9. It is suggested to define the frequency by the HGF register while the LGF register contains 00H, disabling Low Group Frequency generation.
